I think you may have missed my intended point which was specifically in reference to BS. The activity is side vs side but that is not encourage as it is in other games that have similar activities. I haven't played every game out there or even close.. but every game I've played that has a side vs side type instanced area like AO's battlestations throws you into some sort of raid interface. By default that encourages teamplay which is what someone would expect to have if they joined BS for the first time, not knowing what players have turned it into.
If I go to one of the arenas I would expect 1v1.. or if I flag up in Bor.. I expect 1v1. Battlestations isn't 1 man for himself. If people are doing pvp alone, while in battlestations, for the fun of the hunt then they shouldn't have an issue with solo kills being disabled OR (which makes more sense) everyone being automatically added to a raid interface. Those people that wish to go it alone can.. those that want to teamplay can as well and those just solo farming pvp titles will need to go do it in the arena, via duels or via flagged pvp in 'the streets' and won't disrupt the teamplay nature of BS just because they can.
