In the game settings there is no way to disable the chat "tacticool" radio filter, this is very annoying and makes it difficult to communicate with teammates who you can already barely hear.
Party system for competitive does not function. If you could queue with 9 other friends and play a match either comp or private this would be an improvement.
Competitive game lobbies need a "ready" button to avoid all the AFK or none connecting players.
Competitive maps have a playable area that's too large, this should be shrunk to balance the mode.
With Rush, defenders get shafted by Out of Bounds, this makes the game mode greatly favour Attackers.
Versus games and servers are very un-optimized at the moment, I know y'all are working on it but as soon as I see a player and try to shoot them, there's ADS lag and the frames take a tank. Anytime there are lots of players on screen or nearby performance gets crazy bad as well.
US West and US East show very high pings, but the competitive MM seems to run fine.
