Indeed, since Psyren has already decided that all consuming need bypasses Dominate Monster and the Stun condition, it is only natural that "all consuming need" also allows them to Greater Teleport at will, even in Dimensional Locks while subject to Dimensional Anchor. And of course, clearly it gives the Freedom at Will as an SLA.
Because it's totally balanced for players to have access to XP free wish, but impossible for that to actually happen!
