I say keep the chat restriction. The majority of the chat that I experienced prior to 3.5 has just been insults thrown left and right when the match was't going our way.

With the changes coming with 4.0, it's going to be alot easier to use all the different quick chat options. Less actions = more space for quick chat buttons. Especially for us on PS4 (and/or controller players on PC)

Even if they decide to reinstate the chat again, you can always blacklist cringe elitists since it now works cross-server.
