I think that winning a match should give you some extra reward. When I first played Ballistic, I thought that winning a match would give me more xp or something else, well that was not true. I love the game, but pleas add some extra rewards when you win a match. Same for capture point and king of the hill matches. You should get extra points or xp for capturing.
To all the people with the infinite loading screen problem. If you delete your internet cache, history, session,... with CCLEANER (this is a cleaning program for your PC), the game will start normal again. But be warned that ALL your local game proces and files on Kongregate.com will be deleted and settings will be resetted. But it doesn't delete your game proces in ROTMG. I don't know if deleting the internet cache will solve the problem for everybody but it worked for me.
