When chat was allowed most of the games was just half of your team arguing with each other about why they should off themselves for playing a specific way/ using a specific strategy or job.

It was 4v4 then and most matches turned into 4 v 1's 2v2's etc. Rarely ever did all players compete because they were too busy throwing around insults for 6+ minutes.

I don't exactly like quick chat personally, but I don't know that it would be better with chat either.
