Final Vengence...This one has to go and for 3 good reasons. None of them fluff reasons mind you.
Firstly, it's used by Assault players to make up for deficiencies in skill - it doesn't encourage the player to play better. Secondly, it punishes Tacticals and Devs / Havocs for being able to beat Assaults at their own game. Thirdly, it almost guarantees a free kill for the Raptor that requires no skill to acquire. Yes you can TRY to dodge the explosion, but oft times that's not even an option or you can't dodge fast enough or your health is too low. Currently it is a perk that serves to instill rage in others and I can't see any reasonable way to make it work fairly.
I'd like to see it replaced with a perk that allows better freedom of movement with regard to where you ground pound / land as right now, it's fairly easy to predict where an Assault is going to land.
