With progression people doing these types of fights in era once again, and since most comments are years old, here's my recent experience with this guy:
70 Zerker - 900+ AAs, raid geared
70 Druid box - 1k AAs, group geared
70 Beastlord box - 300 AAs, group geared
70 Shaman box - 200 AAs, bazaar geared (bad as it gets)
Went to the west wall as others have said. Harmony on the other dragorns in case they would add. They never did. Zerker tanked. Beastlord spent most of the time on the ground because well, I was 4 boxing and didn't notice. Druid healed and really nothing else. Shaman was just there to throw hots when necessary. No slows landed. No other tricks used. I did use all my zerker discs just to speed things up. Never had any adds. Oh, and I did not have Reptile. It wasn't in the game yet (Phinny).
