OK I may not know what I'm talking about here because I don't have UT2K4, and thus UTXMP for that matter. However, I was talking to some people on U2XMP, asking about how UTXMP was, and it came up that you can switch seats on a vehicle by using the numpad. I've played the UT2K4 demo, and thought that that was really dumb, and I liked how you switch seats in U2XMP better, by jumping in the appropriate side manually. (Similar to Halo.) But, in UTXMP, if you can still switch seats by pressing the numpad keys, that's really bad. Because, if you're in a juggernaut, and you're driving, you could easily just press a button, and taa daa, you're instantly in the gunner's seat, ready to blast that guy in front of you, who was hoping to blow you up before you could hop out and back in again, like in U2XMP. Also, when you stand on top of the juggernaut gun, and the person sitting in the gunner's seat is unaware of it, in U2XMP they have to get out to get in the driver's seat, during which the person hiding on top would hop in the gunner's seat and nail them. If you could press a button and switch, not only do you instantly get change spots, but you're in third person, and can see the guy on top.
