I plan to check Yak out.
I may be a bit distracted if folks are going to assist in the Bad Karma/Rated M battle keep seige battle (If it happens, I'll be arranging for ppl to leave guild to do so, then rejoin us) but I agree that this first ever Yak raid is important. We will get crucial info on how to fight the giant slugoid and take his epics for our own use!
