Wormhole and Rush, Derth Arena, etc

[Grillkick]

My apologies if this has already been reported and I didn't see it. Two things, both dealing with the Paradox Mage ability Wormhole:

1. An enemy that uses rush will be unaffected by the talent Wormhole, ending right on *top of it* and still attacking. This is bothersome as it defeated the purpose of why I was using it. I'm not sure if this would be the case with other similar abilities as well (Cursed's ability, or even someone using an item with Bone Grab for a neat combo)

2. In the Derth Arena I used Wormhole for that purpose (second guy that always rushes) and noticed that the exit wormhole was randomly placed outside of the walls of the arena! Since that area is unreachable it would be a good idea to prevent wormhole exits from spawning there as it could possibly leave someone with no dependable way to get to an enemy after the spell expires or a way to get back inside.
