This question keeps coming up on the forum, so I thought I'd post my reply here so I simply have to link to it for each new thread. ;-)
Blood Fury - free AP trinket basically; just under 250 at 70.
Command - +5% pet damage. Extra damage across all specs.
Hardiness - +5% resistance to stuns; great in PvP, and helps with kiting...also synergises well with Surefooted which includes +15% resistance to snares in the Survival tree, if you go that path.
+5 Axes - Legacy and the Arena Hunter weapon are both axes.
Or...you could choose a Troll for da look, da rhythm, and da voodoo, mohn. ;-)
