Someone should make a World of Warcraft battleground map, such as Warsong gulch and make it CTF. I'm trying to but, I know, I suck at making maps. So if any of you top forgers would be nice enough to make a WoW battleground map, then you'll have my DL for sure.
WoW =/= Halo. With that being said this could be interesting. High health/low damage and swords could be interesting, spartan lasers could simulate casting. Carbine for hunters? Camo for rogues? Regenerators for healers? Lots of different things to try. Speed boosts could be easily simulated.
