Chalk up another piece of evidence for just how trivial the old world stuff will be when Wrath releases -- here's a video of a Hunter at level 77 (on the beta servers, obviously) soloing the original raid boss herself, Onyxia. There's a little more info about how it was done over on the WarcraftMovies page -- the only way to deal with all the whelps was to max out AoE, so he used a special talent blend just to do this. And it looks like he just dodged or ate the Deep Breaths, as I doubt even a 77 Hunter would be able to put up enough "dots" to down her before she can do too many. Roar of Sacrifice also got a lot of usage -- it's a pet talent that lets a Hunter avoid half of his pet's health in damage. And he says the two-piece set bonus from Hunter T5 helped a lot, too -- over the fight it added up to quite a bit of healing.
Not too shabby. And at 77, this means there's still three levels (not to mention all the endgame gear) to grow. Maybe the fact that Blizzard is revamping/replacing the old endgame isn't so bad after all -- when it's this easy for the highest level players, it's time to move on. Unless, of course, they make soloing Ony an achievement.
