It made more players passive, the game is not fun. You heal up and a random explosion or a random spray bullet tagged you, taking away your heal.
This would make sense in a 5v5 game. Attrition in a chaotic game is absurd. I really hope it does not return in the series.
Same with ammo attrition. I was convinced that this was okay. It's not. It's bad too. You can keep the grenade timers the same but also needs to get rid of that Attrition also.
