Someone put together a rough nin rotation guide.
I actually misread the original patch notes (thought Huton was 70second cooldown not duration), and I'm kinda flabbergasted at how powerful ninja seems to be. They basically can have GL3 up full time with no cost, have 20% extra damage, have higher potency then mnk, have base fists of wind type trait for boosted run speed(unless that was cut), can silence at will, can TP regen themselves, have decent aoe, have great burst, and to top it off can provide a 10% damage buff to party.
It's like they gave them all the best parts of MNK/DRG but gave them none of the bad. Seems like only "downside" to the class is remembering mandra combinations, but people can just macro that.
