UTXMP should be asU2XMP in this aspect.. You cannot kill a player in a vehicle without killing the vehicle currently(TMK,) at least that's the theory, even if it's not working 100% right now. Also, I've been trying to talk FMI for a while into coding XMP style vehicles(ie. enter hull to drive, enter turret to shoot.) There are some issues with the Juggernaut being overpowered due to the ONS style stations among others. (random example.) Personally, I think the vehicles should be crew served to reach full effect. Currently, I can drive off in a raptor, and switch between stations to keep up a volume of fire by myself while the vehicle is moving. I don't like this or certain tactical changes this forces. In U2XMP, you get into a duel with someone, outsmart them and move towards a vehicle in the course of battle, jump in and frag them.
All that being said, I don't think UTXMP is finished enough to really discuss the issue. Also, the vehicles are sooo different in balance between UTXMP and ONS it's insane. Being able to easily add player made vehicles in UTXMP is a huge asset. However, adding ONS vehicles without significantly changing their functioning is a huge balance issue. The Manta and Cicada are perfect examples. It's doubtful any of the XMP weapons would be more than marginally effective at taking them out with the rocket launcher being the only viable yet marginal choice to do it. Remember, vehicle balance was rather thought in U2XMP and changed around a god bit during the beta for balance( and indeed between 6497 and 7710 for the Harbinger.)
