#3: create a Dota or Tower defense mode for The Casual crowd
Coh1 Tales of valor had a moba style gamemode, never got to play it though. It looked like fun when I opened it once, as well as that tank-on-tank arena game mode.
I doubt we will see such a thing though, devs thus far dont really seem passionate about the game. So far the only dev I saw with sparkles in his eyes when talking about coh3 was Marco.
