GK pre taunting under Revan

The usual. Bastila, GMY and Jolly.
Mine is DR, Nasty, HK, Sion and Nest but I switched her with Kru. I don't remember if it was with Nest or Kru.

I never seen it but what you said is probably what happened.

I ran JKR with GK in arena every day from JKR was first released until Darth Malak came along. Not once have I seen GK get pre-taunt. And I've played A LOT of JKR mirrors ... A LOT!
