Hey, i know my first guide to GM island was totally bad, because its was on patch 1.2.3 or something, a really old patch !, whatever,
if you want 100% in black temple when you raid with you guild. try to summon you flying mount, and the ask a warlock to summon you forward the port to the instance and when you appear, you have to fly in the port, when you are in, you will still have the buff with you flying mount, and will run with 100%, i have tried it, on maelstrom with buliwyf, he's human paladin lvl 70, . good luck :wave:
