Just came out of a Wintergrasp Epic BG where a Warlock was able to teleport the entire team under the stairs in the Sunken Ring Workshop area, where nobody could move or attack. I don’t have any problem with the talent itself, but I don’t think being able to trap the enemy team in unescapable or buggy terrain is intended?
Same thing in AV and many other maps. The talent is broken because there are too many ways to exploit bugs in the game.
