So, for instance, if I have 6 buttons, originally for Spinning Edge, Gust Slash, Aeolian Edge, Dancing Edge, Armor Crush, and Shadow Fang, the main idea is I can reduce this to 3 buttons:

If Spinning Edge:

1 Gust Slash
2 Shadow Fang
3 Spinning Edge (re-do... for the sake of prepping Shadow Fang for an enemy that has a GCD left to arrive?)

If Gust Slash:
1 Aeolian Edge
2 Dancing Edge
3 Armor Crush
(No Re-do Spinning Edge, because there's virtually no situations in which you'd waste a combo. Except maybe those pacify these mobs leve quests... in which case you'd just use Mutilate at that point anyways.)

Certainly easier for DRG, especially, as you said (just TT-VT-FT-F&C/WT, ID-DB-CT-F&C/WT, 8 in 2), though at the same time, all this makes me wish these moves still had value outside of their respective combos, so they didn't just feel like single 3-part weaponskills.

Monk would probably just be each of the three options per stance, I take it?
1 Bootshine / True Strike / Snap Punch
2 Dragon Kick / Twin Snakes / Demolish
3 Arm of the... / One-Ilm Punch / Rock Breaker

Would definitely be nice to be able to do this without having to change out hotbars via macros each time.
