I personnally like what some Modders made out of BF42, by setting up a moving spawnpoint like a Plane (f.e. the AC130 in Desert Combat)
Here you could go further and make it possible, that the commander starts a Blackhawk, coming out of now-where, that moves into the Target Area, lands, and acts as a spawnpoint for several secounds.
(maybe this should only be avaible if some friendly forces are nearby the designated Area)
Well...this requires a commander
Anyway, maybe it would be nice, that you have some commander with only very few options like reinforcements(the top mentioned blackhawk) or supply drops.
Well...another option would be to remove the spawnpoints from the squadleaders and instead make the vehicles (HMMVS, LAVS, Blackhawks...) the new mobile spawnpoints prerequisiting that there is already a player inside.
just a few Ideas me and my friends from http://www.k-clan.org had !
