First off, one of the best games ive played in a long time. Thanks for it 
I forwarded my ports and it solved almost all of my connection issues. More focus should be put on that topic. When someone leaves during midgame and everything stops and we have to wait for a min before continuing, thats irritating. Needs an updated chat system. Should be able to chat in the custom game room. Also a pm system would be nice. Game creator pings should also be displayed. Commands for framerates etc would be nice.
I think its still to early to start with any nerfs. Iearned adjusting builds and playstyle fixes alot of that. The minion AI should be looked at, they dont like to go around corners on some maps. Also a function to flag the routes for reinforcements coming out of the portals would be cool. Idea: you could drop flags that would change the route the reinforcements took.
Again, overall I love the game, ill hang out till you guys fix things, although you do deserve a slap on the hand, for not dotting your i's and crossing your t's.
