So alot of perks are glitchy and dont work. Like cooling snyc (sad face)
I can appreciate that if one attack def/buf perk goes they all gotta pretty much gotta go. Thats a fair trade off on both sides. The health both is only 15 points and that only makes support XXL Hefty.
I will argue that observant should stay no only cause I like it, but its a counter to mudding up constantly. Also, its not a cheap perk if I remember right.
Anyway
All perks need to be revisited to make sure that one, they work in the first place, then we should tackle redoing them.
I think some perks should be class passive too a mentioned, same for fireteam, give classes a passive perk that applies to that class
