Ninja, The problem job and some ideas to change it.

[Selvokaz]

1) It's a flank finisher, which sometimes make it better than Aeolian depending on positioning.
2) Aeolian does more damage than Armor Crush, because Armor Crush increases the Huton timer.

Armor Crush has its purpose. There is no sense in removing it unless you plan to change NIN even further. Just removing it isn't good enough.

I didn't say just remove it I said roll it into Aeolian Edge, is me saying Fuse it into one attack. Aeolian Edge already has a rear combo bonus, all you are getting from armor crush alone is the increase to futon duration, hence my suggestion again Fuse Armor Crush with Aeolian Edge so that Aeolian Edge does what Armor Crush does and drop Armor Crush.

Basically it boils down to the futon duration being uses as a unnecessary anchor to justify armor crush's existence, as we move forward new skills are going to be added to the classes, fusing armor crush into aeolian edge is the most logical design choice to lessen the rotation bloat of ninja as new skills and abilities are added, we are about to get a increase in role action slots, which means peoples optimal rotations is going to increase anyway. I don't how to simply this enough, adding the benefit of Armor Crush to Aeolian Edge just makes more sense.
