Aside from some of the negativity I'm seeing in some peoples' posts, I just want to put something out there in an effort that might actually help. First of all, there is no such thing as spank and tank in the raid game. Sure, even our guild calls it that sometimes, but if anyone literally does spank and tank, they're going to get spanked. Key factors in a fight, especially a straight melee are critically important, especially especially at the start of a fight. Obviosuly, this is when the mob is his strongest - no debuffs. Of course great skill won't help if a mob that was last done with 30 people is relatively unchanged, but the idea of spank and tank should be abandoned once you progress past Lord Jerzakt, as uber as he is.
Having said that, slowing early, massive early heals, a high aggro tank, melee debuffs, and aux tanking are all very important aspects that, if executed right, could very well make a hit on a straight melee more successful.
Also, do you know if he can be stunned??? :monocle:
Good luck and if you try him again, I can bring some spank!
