Word. The critiques are all fair, though I did add some cover for non-flying races. Not to mention the teleporters help them move quickly, too.
I agree: having better cover right on the bomb sites is a good idea, so I'll chip away at some sensible tweaks. All I can say about spiderman and human is that if you miss your mark it could hurt you. There's enough space to kill anyone from a fall, so there's that to consider. All in all; thanks for the feedback and for not sounding bitchy about it. This helps me get better at this sort of thing.
I'll update when I get a better version done. Thanks!
