@Kiwi: Balance would be messed up, true, we already see this in one map... it's called Bed something.
@CATAHA: Like I said to Kiwi, there's a map that was ported. I've played this map in invasion on UT2004, and I remember it very well. However someone ported it to Tremulous. There's a map, Mines of Moria and it was a near-like replica of the actual thing. I'm curious, how one gets it from one game to another. It would be quite interesting. "Bed" something, is a map that has this screwed up balance, yet people still play.
