I voted to disable all non alpha incarnate powers.
Don't create a copy of the zone that allows incarnates. This would only work if we had a large population of PvPers to where you could still get good coverage in both instances of the zone, which isn't the case.
Echoing what @M3zsaid regarding the nerfing of archanos or , particularly the spider queens. They are grossly overpowered relative to the Longbow.
