Concjumping

You can conc jump as a scout or medic using your concussion grenade to push you in whatever direction you chose. Getting the right angles/height on the jumps can be difficult and takes some practice. There are basically two ways you can go about doing them - dropped concs and hand held (HH) concs. The latter (HH Concs) being the more difficult of the two. Dropped concs will in most situations give you enough height/push on most maps and is the easier of the 2 methods of doing. Hand Held concs require a set of things and can be unpredictable. For either technique keep in mind you can/have to steer yourself in the air after the conc so the enemy can't predict where you're going and it gives you more precision on where you want to go. Get good at steering yourself in the air with dropped concs and you can get more precision on your landings than with HH concing. For most complicated jumps (eg. over ruins on Epicenter) HH concing is a must.

DROPPED CONC JUMPING

It's a good idea to master this method before moving onto HH concing. Using your grenade timer, take note of when the grenade detonates on the timer. Dropping your conc for the jump gives you the advantage of having less of a chance of screwing up the jump, which is key during matches and in areas well defended. To get the most height out of a dropped conc note when the grenade detonates on your timer and jump a second or close to a second before the conc detonates so that you're in the air when it dets. Try jumping at different times on your timer and you'll realize that jumping right when it detonates won't push you as high as when you jump a bit earlier from when the conc detonates. The farther horizontally you are from the conc cone radius (the radius that the conc will hit you in) the farther you'll go horizontally. For vertical height it shouldn't matter where you're at in the conc cone radius (horizontal wise) but for distance it makes all the difference. If you want to move more horizontally than vertically make sure you're standing more away from the center of your conc grenade in the direction you want to go. If you want to go straight up you'll get the most push from the center of the conc and jumping just a bit before it detonates. Move more outwards from the center of the conc depending on how vertical/horizontal you want to go. Test out the different angles you can acheive with this. If you want to go very horizontally, drop your conc and run as much away from it as possible while staying within its blast radius. Make sure you're still moving in the direction you want to go when the conc dets so the momentum from your movement is increased by the conc. There's no need to jump if you want to get the most horizontal angle as possible.

Enemy D can easily defend vs. the dropped conc technique by shooting rockets at the conc itself since you'll be attempting to use the conc to perform a jump and you'll have to get near the conc. To counter this, try to do your conc jump when the enemy isn't looking or when there's lots of noise going on. Sometimes you have no choice but to do the conc right away but always try as much as possible to make your dropped conc not visible to any enemy D. Instead of dropping your conc around the corner drop it so it doesn't bounce around the corner where people can see it there. Remember your conc works through walls so you can drop it on one side of the wall and still get in its cone blast radius to jump on the other side of the wall. Also, try not to drop your conc right away after priming it since that gives more time for the enemy D to react to yourself. Hold the conc until it's about to detonate then drop it so the enemy D will see it just before you do the jump rather than 4 or 5 seconds before you do it. This gives them less time to shoot you. One technique which is useful is to hold the conc and a second or half a second before it detonates quickly turn your aim in the opposite direction that you want to move and release it then aim again in the direction you want to move while you're in the air so the conc blasts you in the direction opposite of where you released the conc.

One more thing is the farther away vertically from the conc you are while in its blast radius the higher you will go. Drop your conc in an area below you and jump onto it just before it detonates while you're a meter or 2 on top of it and it'll send you flying really high.

HAND-HELD CONC JUMPING

Hand-Held concing is something which is dependant on a few things. First is lag, second is your FPS, then your timer and your timing. Lag will vary what times you should jump , making it difficult to HH conc jump since your lag is constantly changing. It's hard to time when you should jump based on your lag. It's usually best to jump later than you usually would for HH concing but really with a ping over 250 or so it's better to just go with dropped concing which is very much less lag dependant. Your FPS affects HH concing in that if your FPS goes down while you have a conc primed, the conc will detonate at a different time than usual. This makes it especially difficult to HH conc in laggy places with lots of things happening on your screen. For example a suddent explosion on your screen or someone suddenly appearing on your screen could affect when your conc detonates. You'll notice this when your conc goes off different from when it should on your grenade timer.

Your grenade timer is what you should be using for anything that requires grenade use including concing. Make sure you know when your conc detonates on your grenade timer. I can't give a definite say on when to jump for HH concing since everyone has a different timer. The only way you can get good at HH concing is to practice it on public games. Don't practice it on your LAN since you have perfect FPS/lag there and will be able to pull off the majority of your HH concs. Practice on public games. Prime your conc and jump just as the conc detonates or at different variations test out yourself the best time to jump. To get different angles on HH concs you need to move in the direction you want to go. If you want to go up and horizontally then move forward and jump in that direction; the time you jump affects your angle/height. For vertical movement you won't want to move horizontally as much, instead move horizontally just a bit before it detonates and jump (again something you need to practice in order to know when to jump to get different angles).

All in all HH concs are hard to defend since it gives the denfense little time to react before you pull off the jump. You can get past enemy D by surprise. Pop out from around the corner after you've primed a gren for a second or two so you do the jump just as they see you. HH concing gives you more flexibility of movement- you don't have to get to a static position on the ground like you do with dropped concing, instead you can jump from anywhere you want (within a certain degree, sometimes you have to stand in certain areas to get to where you want to go). Hand-held conc jumping and dropped concing both have their advantanges and dissadvantages, so it's good to excel in both of them.
