Solo queue is always a coinflip, regardless of game and genre. What makes it worse is class/character imbalance, which is a pretty huge issue right now. There is a monumental difference between the best jobs and the worst jobs, e.g. between a WAR and a GNB, which makes the coinflip seem even worse than it has to be, especially if you're playing one of the weaker jobs. This is something that should hopefully get better in time.

That being said, they should absolutely bring back the chat for ranked play, even though I don't see that happening because of their general stance on the matter. The quick chat was most likely their idea of adopting ping communication from MOBAs but it just doesn't work nearly as well in an arena-type MMORPG mode.
