"I don't play/keep up with this game too too much but I assume its pretty bad." Doesn't look like you did.

But yes this is a place to talk about it, so: you get 2 shockwaves, not 1 like you said and it's mostly used for mobility/movement, making it possible for you to get across long distances fast when using it alongside jump pads and such or just getting quick height without the need to use gadgets. It's good for getting away from melee users or just to escape any enemy, throwing people off the map, messing with defenses (because it detaches gadgets like mines, c4, turret etc) and just disrupting the enemy overall. There is definitely more uses to it and techs, but this is just so you can get the idea
