I see much more (successfull) spam than before this change. I don't really care though. I don't even know why I still have a inf weapon.
Aside those very selfish statements, I think the melee animations should be reworked in order to make this change work right. IRL, you effectively attack from the start of your "animation". But IRL nobody is a widely-swinging moron like in the game. Previous attack timings were sort of more accurate because they matched what a true RL attack would do, despite the retarded look.
