Well balancing is very important however there are quite a few bugs and issues I'm starting to get annyoed with. My biggest pet peeve is Server Losses. Sometimes it feels like I'm playing against the server, I've lost hundreds of MMR points thanks to the damn servers. Honestly I think they should introduce no fault server losses, meaning if you "lose" due to a server issue you dont lose MMR, though of course then we'd likely see a bunch of "disconnections".
