Getting to him may be difficult, but taming him by himself is not really that bad, especially if you are already at level 85. I tamed him at like.. 83 I think it was? He only took down about half my health and nothing interrupted the tame itself..
(except for the healer trying to hela me, stealling aggro and wiping my group
)I was a draenei at the time and used the racial healing spell at the time too-which was handy.
