There's no need. Ever done the CoP 8-3 BC? You can target players, talk with them, trade with them, etc. But you cannot commit actions on them (Cure, Raise).Originally Posted by BRP
The same holds true for the other battlefields in the game. You can POS into a battlefield arena, but if you don't have that battlefield access icon, you can't cast spells on the players inside.
(Although I imagine it still would be possible to claim a white monster, or pop a chest inside the battlefield. Haven't tested it.)
