Yes, good post!... bF2 does have these groups, sadly they arent used so much by mappers....
Im surprised you find spawnpoints inside the cap radius???.. on what map? on what flag? Report this as a BUG as it is against FH2 standard to have these. I will personally nag at the mapper to move them out of the capzone... Now, however on some african maps, it is quite impossible, El Alamein for example, those outposts, that the capzone cover almost the whole outpost... it would seem weird/unfair that infantry spawn outside their own perimeter of trenches, sanddbags and barbwire, if there is an emeny tank inside the radius...
BF Heroes have a feature coded in to the spawnLogic that each flag has different spawnpoints for each team (Royals spawn on the west side, Nationals on the east for example at RoadBlock on Victory Village) this feature can be somewhat replicated in Fh2 with dummy flags (the reason why sometimes you see "the enemy has captured farm_dummy) but it still isn't perfect. It's used in some maps, but it is too unfriendly technique to be globally used on all flags in the mod
