This bug probably exsists since release and currently people don´t run ranger in tournaments so this is not big of a topic for most people, which doesn´t mean that it should not be adressed.
I just tried to rezz myself in a duel and it didn´t go off, but i was sure i activated it, so my Teammate let me revive to check if the rezz was on cd and yes, it was on cd because the pet starting moving.
How can you not fix a 180 sec Elite skill ?
