I'm a 41 feral druid.  I just needed Herod to finish my quest and couldn't find a group.  So I stealthed in up to his door. killed the mob across from the door and the pat.  (I died twice cause they ran and aggroed other groups but I got those guys down.)  After I rezed and stealthed back to his door, I stood as far away from the door as I could to change form to open the door, than changed back to Cat, and stealthed in to his room.  I soloed him.  When he went into his spinny thing, "blades of light" I backed off and hit my Instant HoT and Regrowth, (a 2 sec cast, its a HoT with some upfront heal) and switched back into bear to comtinue the fight.  I had to use a mana pot, and I had to inervate myself but I got him.  I had time to switch to Cat form and stealth while the little guys ran in.  I went to the point farthest from them, changed back to druid form, they didn't aggro.  So I set up hurricane, and it killed a bunch of them before they canceled my channeling, I switched back to bear and killed the rest easily.  They really don't have hardly any HP.  Too bad he doesn't drop anything for druids or i might just farm him.  At least until the druid nerf patch comes out.  /cry
