First of all : nice installer, the Phade picture was a little oversized though :)
Second of all : clear interface, hurray !
Here are some suggestions :
- if you host a game, can you auto-set the number of players to 5v5 ? now its 0v0 in auto.. which is a bit annoying
- can you close the local game window when you start the game ? so it doesnt stay open while you play and then its hidden when you go back to the main screen.
- ingame, you create more space for item slots .. but you dont use it all .. example necrophyt book (+10 int) has a menu for him alone ...
- striders + mock dont go in cooldown (intended?)
- .. overall, very neat !

Can you make some AI ?
