Stamina has big crit hit, big heals, many buff passives to attack power and crit, very easy to get AP to over 3k, unbuffed.
Magic? Avg Crits , Long weak heals dot..(unless you a temp) 1 decent crit buff, 2500 SP, you have to push it.
ZEN, I hope with the new Expansions coming up, you give some love to magic skill lines.
I am playing now a Magic NB, been playing stamina NB since beta, and I am shocked to see the big imbalance between stamina and magic.
