To be honest I'm tired of testing instances, instead of introducing a buggy instance, test it a week longer.

Hello
Can you be specific on which "bugs" you're talking about? So far we only were reported a few and most were fixed within few hours, none of which were gamebreaking effecting the play of the instance bosses.
Did you attempt a previous boss and wipe before starting the next one?
