Really depends what you're gonna do. Some people start Gvg'ing/Pvp'ing/Whatever'ing at very low levels (5-100). Attack, Defense, Armor, Damage, are good, but HP isn't that helpful. If you're just gonna level, then put them all in damage.
actually... HP *might* make for a pretty awesome base... get into a Armor Set, then use Vigor, top it off with Chi Strike... KE, etc... i spy a tank with a pretty heavy hit >.>
