One thing missing from Crysis 2 was a chat indicator while in the game. This was present in the lobbies, but not during the game.
We couldn't tell who was speaking on the mic unless we already recognized their voice. It's nice when a little list pops up of names that are inputting sounds, so we know who is talking at all times.
Yeah, Mass Effect 3 also svcked hard because you couldn't know who was talking and you didn't even have a chat option! Is it really so hard to implement? How are you meant to have a social team experience if you can't communicate with your teammates properly?
