Game would be infinitely improved by removing non-premade chat functions and/or re-adding chatrooms
as long as the policy is to ban or otherwise punish people for being horrible racist dickbags or (on a less generally-beneficial side) for getting trolled particularly hard repeatedly, there seems like far more drawbacks to benefits of even having a chat feature - Pings cover all the objective-based communication you need, and emotes the BM or very occasional thumbs-up.
just a thought.
