Ok I guess I am really really missing something here. I am 64 x5 shamans wtih 5k health 6k mana now. I STILL can NOT kill this boss. What i have tried is to pull the 2 low lev elites up teh ramp to not agro the rider. Run back in and drop gorudning totems for the dragon. As i get close to him he keeps running away to the point where if i do get closer the rider will agro.??? I cant seem to get close to dps the dragon down to 30% w/o agroing the rider.
I just successfully did this strat for the first time last night. I remember reading about this when I was leveling and thinking about how easy this boss was going to be. The problems that I ran into was running out of mana. Don't stress yourself out too much about failures early on. As your gear gets a little better you will be able to do more. I don't think it is worth wasting time on trying to kill this guy. Have you farmed all the stuff out of blood furnance you wanted?
