Getting up there is easier than it use to be, goblin glider to the rescue, cheap and anyone can use it. The drop rate is not great, I killed him like 15 times before I got one. I have probably killed him another dozen times over the last year or so and never got a second. If memory serves somewhere between 3% to 4% drop rate.
Respawn of 30 to 60 minutes, with bad luck you'll be there a while. What I did was park an alt there and did other characters while I waited. Checking back between things I eventually got it to drop.
At 100 I would think it a simple fight, if you have an alt a few levels lower I would think that still doable. With the right class he was soloable at 90. I never managed it with a priest or hunter though. Not saying it wasn't possible, I am just not as nimble as some people are with their class.
Boils down to if your time is worth the wait or just splurge and buy it.
