Ninja: Walk in shadow.

[Eardstapa]

@ Eardspota : Ninja has A LOT of steroids as well as more than just a couple of high potency attacks. Huton ( 70 S 15% ASPD buff ) 10% Slashing Debuff (20% with a warrior using storms path while also giving you more leeway in combos) Poison as well as a 20% DMG +(possibly more with trait) 10% DMG from Trick, and an OGCD that will let you always crit dat Raiton when its up. Those are some serious steroids. and we don't even have the traits yet!

Those are hardly steroids as power as Monks. A 3 minute Cooldown to make Raiton crit is hardly a 'steroid'; Rather, it's similar to Perfect Balance. You also failed to read the patch notes, and I do not mean to say that offensively.

EDIT: Straight from the patch notes;
Dancing Edge
Delivers an attack with a potency of 100.
Combo Action: Gust Slash
Potency increased to 260 when executed from a target's flank during combo. Combo Bonus: Decreases target's slashing resistance by 10% and HP recovery via healing magic by 20% Duration: 20s
Cannot be stacked with the Storm's Eye status.

Trick Attack only lasts for 10 seconds, with basic GCD, that is only 4 skills. And it can only be used once a minute... Poison does offer a sort of steroid, but you have to consider, Monk gets 27% from Greased Lightning 3, 5% from Fists of Fire, and 10% from Twin Snakes. As well as an overall 6% increase from Dragon Kick, and the lower GCD and auto attack delay... 15% attack speed increase.

Compare this to Ninja, who at best will have a 20% boost from poison (Pretty sure this is with the trait, dev ones were leaked a while ago. 6% overall from Slashing Debuff, and 10% from Trick Attack, which Monk will also have access to if they are in the group. Plus their 15% attack speed increase, which may or may not be similar to GL3 (I am assuming it is, since it is the ONLY other thing in the game that is comparable.)
