yes, night elves are really good warriors.
Agiltiy is what your chance to crit is based off of. Take cruelty, Deep wounds, a Two-handed axe, axe specialization to greatly increase your chances of crit'ing.....and with an already-high damage weapon, that will hurt. Watch a crit-Heroic Strike with a 2-handed axe.....you'll be glad you went night elf. Personally, I went human, and even then, I crit at least twice a fight...with your higher agility, you'll probabaly be able to get off a third, maybe even a fourth one. It all comes down to play style.
