The revenge booster is way too powerful for a slot 2, it takes no skill to use and makes the entire battlefield into a minefield. So many times where I've killed some guy who was trying to blindfire me but I got killed/knocked down then killed by his revenge grenade, or me trying to level up my Cloaked booster but get killed by his revenge grenade before the stealth kill animation was even finished, or that the throwback window is already over by the time the animation was over.
That, and the times where my teammates are killed but I got teamkilled by the revenge grenade that he dropped, since I can't throw it back, but he obviously couldn't care less since there is zero penalty for killing a teammate the first time.
Please ND, make the game better by increasing the throwback window for revenge grenades and let the players throw back their teammate's revenge grenade, or make the revenge grenade a Teamsafe grenade
THERE IS NOTHING WRONG WITH REVENGE!
I was able to stealth kill, taunt and throw back their revenge grenade all within the timelimit. Out of all the boosters this one is pretty balanced. My only suggestion is for level 2 and 3 to swap themselves but what are you going to do?
Move it to slot 1
Make it where it only works after being killed 2 times without getting a kill
Make it a kickback with a low medal cost.
How would any of this make it useful?
Turn it into a kickback, so it's a kickback that only helps when you die. No one would even bother using it unless it automatically dropped megabombs or cluster bombs. Also dying 2 times without getting a kill? Well what if you don't get the revenge grenade kill? There's no point in using it anymore, that booster that displays the location when you die 2 times without getting a kill is a more effective booster over what you suggested.
It should either have a second or two longer to explode or change level 2 to level 3 and make it so you always drop a grenade at level 3 instead of level 2.
