hia chris
the way you were going at the start of your post mate i thought you were going to cancel domination!
playing accross the maps have always gone down well
you could do the command post and bridge as a Domination style - holding both flags scores points but your correct that the respawn points would be tough. i think the bridge spawn point would have to be down by the firing range and the village for the coomand post and there might be problems with respawners getting attacked and people not sure where the out of bounds are
so how about command post and bridge having a flag in the open ground between the rocket tower and sat dish and at the approach of the bridge.
the two teams can respawn in the trenches and in the woods at the back of the the command post and crazy attacking runners can make a break to touch the flags and win points
so a tactical attack team working and fast running respawn style straight accross the field with the rule of DONT SHOOT ANY DEAD PLAYERS OR ELSE YOUR TEAM GETS A PENALTY 100 POINTS and less worry about boundarys
the push style you mentioned will work out fantastic without much worry
the village to castle sounds very interesting
hope the weather is like this next week
