I've got a level 50 grav/kin, and Ive tried out the new Wormhole on the test server. I like the wow factor of the AoE teleport, but it does, as many have noted, drastically change the tactical implications of using Wormhole.
Regarding this powers control factor, what if it was changed so that it was *un-resistible*? Then wed know exactly whats going where. And the certainty should offset the downsides of the AoE change.
