I'd be opting for reup time for jeeps, you hit the sucker good he gets 2000 sec jeep restrict. Not as drastic as some people propose but coherent with the arena acks DM. Still dont know if this is the best option. But i like it, it's somehow neat
Jeeps are ok and I think, everybody should have the chance, to defend a field in a jeep - but only one time! After beeing killed in a jeep, give him a restrict of 600 s.
