Huh, i had the damage turned up, and still no dice with a Warthog. That's weird... I agree that the points could be better written, but I as a developer would rather have this type of feedback than none at all. People care about this game enough to mention this stuff at all.
It's just so frustrating when there really wasn't any reason to change it so much at all other than the flood might look cool to some people. I get that, but that's no reason to change core gameplay mechanics associated with the game types, especially when, at least as far as I knew, many more people play custom games than play normal infected playlists. I played it once or twice before I got bored, but that's just my taste. The issue is that it take many important things away while not fundamentally adding a whole lot other than a skin for zombies.
