This is, so far as I know, the only pet in the game with two distinct whole-team damage abilities, one per pet (BONESTORM) and one divvied up among the living team members (Grave Destruction). That's over 1400 total damage to a team in two turns, plus the potential for a single 660+ hit on the last opposing pet standing...on an undead with that annoying "gotcha" round AND over 1600 health.
That might have something to do with the rating.
Handy note for the flight path method: Moonglade is, at the server level, part of Felwood. Flying in from Moonglade will not reveal spawns. Flights originating in Ashenvale or Darkshore or Hyjal will (haven't tested the Everlook FP).
I was 7 for 7 until I got to Viscudus and the Twins (all the MC and BWL pets on the first run). Either I had one hell of a run, or the MC and BWL pets have significantly higher drop rates.
