Worgen are also the strongest. You used to be able to glitch out at level 1, but I haven't tested that this patch. While the 2 min racial is nice, 2 mins is a long time. You also have charge and swiftness potion. Human for the 2 min trinket and extra trinket slot, is hard to ignore, gnomes get a limited use extra trinket racial, dwarves and draenei, as well as the previous favorite, NE, are probably the worst now.
2 min CD sprint + str and crit + shadow and nature damage reduction, but no shadow fear resist or save 3 mins on trinket and extra stam/haste. Tough call.
