Surprisingly logical. I more or less like this change. The devs would need to shift the animations with the name change as well to keep everything nice and tidy, but I like it.
I disagree not because I don't want the rotation changed (it needs to be changed. Seriously.) but because I don't agree with how you want to change it. Right now, we have 2 20-second-long buff/debuffs. Or, more accurately, a 20 and 18 second duration ability. Dancing Edge and Shadow Fang. Putting Shadow Fang after Crush Armor makes no sense, as that's just "You permanently have Huton pending boss mechanics." Having AC after SF makes less sense for the same reason. If you apply SF, why wouldn't you just crush armor? Even with changes in potency, it'd still be required. You could lower the amount increased, but AC fits best as a "You use this to rebuild Huton if you need to." And it should stay this way.
The natural combo is Spinning Edge -> Dancing Edge -> Shadow Fang. The only change that would need to be made is that DE might need its duration increased, along with SF. Naturally, the potency of these 2 abilities would need a mild adjustment as well, but the current NIN combo is 2 3-length combos for every Shadow Fang, and since DE needs to be up anyways, may as well put it before SF.
Another alternative is to make DE its own combo starter that chains into Shadow Fang. The devs would just, again, need to adjust potency as necessary. Though I feel this might be less skill-intensive on the rotation than making SF a 3-length combo.
Either way, the nature of how DE interacts with AE and AC needs to be changed, because right now, the NIN rotation is just a mess unless a Warrior is present.
The problem is less the range, and more how horrible the UI is for ground-targeted abilities in combo with the range.
For instance, if they made it teleport you to the closest point to your mouse cursor when casting the ability outside of max range, it would be substantially more useful. Extra range would only serve to mitigate the horrible UI issues.
Hell, I kind of wish I had the option to simply "Target GTAoEs at closest point to current target" as an option, honestly. That would also fix the problem, and make GTAoE abilities not a horrible mess to cast.
25 yalms isn't bad. 25 yalms with many fights that have distances exceeding 25 yalms in addition to a badly designed UI makes 25 yalms bad.
