And also; enable pumps, allow more of the corespiral (w ledges) and make pet-teleportation possible in combat instead.
This should fix several unfair scenarios (which I will not mention) aswell as making ranged, subterfuge-combat, sniping and stealth possible to play & enjoy in AO. There is blindremoval-repetoir, retreat-possibillites etc should one be strategicly shot at from above when capping core.
Capping could for example disable and make u immune to roots.
