been doin this now past two runs, works perfectly.
Basically, keep the last troll sheeped, and the entire raid run up the stairs and just before the top turns left, and jumps down a bit onto the ledge. (at this point mando is just sittin on his raptor at the very top of the stairs). have MT positioned at the bottom, when the sheep breaks, MT pulls him to within LOS of ur raid and kill it, at this point Mandokir will race down, jump off his raptor and attack MT (raptor will simply stand by his side doing nothing)
MT then simply tanks him up, and its instant DPS call with healers overhealing the MT as ranged DPS goes full out. He will never run up, charge you, or anything, so DPS classes literally just stand there and open up, even when whispered, he wont charge
Once dead, everyone jumps down, easy raptor kill... and Loot
ill update this with pics on next run.
hope this helps +k always nice
