Justify this, I dare you - I double-dare you!
What are you smoking out there in Austin?! The game has so many stupid bugs-that-cause-death-or-a-wipe that now you see fit to make sure everyone dies when a glitch occurs? Or maybe you don't want to allow out-of-combat resurrection and make the whole damn party wait 5 minutes between each combat rez when SOA bugs out after he's dead, but left a mind trap or ball lightning on the field?
Seriously BW, What Gives? You already made damage interrupt the "casting" of Exit Area, so why go to this extreme?
