Job action combos one button

[Shurrikhan]

tbh, a few basic combo of some jobs could be consolidated to one button.
out of the jobs I've been playing lately, RPR, GNB and DNC comes to mind.
the RPR slice combo could probably be reduced to one button, and their AoE combos. The scythe combo as well xD
That's 3 free buttons right there, and functionally nothing would change.
GNB can stack edge/shell/barrel to one, like they already did when you used Thancred against Ranjit.
and I'm sure there are others as well.

The same would occur for jobs with multiple combos; it's just that each combo would need its own button.

DRG, for instance, would need a total of 4 GCD keys: Full (+2), Chaos (+2), AoE, Piercing Talon.

(7 buttons saved, or 8 with Jump -> Mirage Dive.)

NIN would need a total of 4 or 5 GCD keys: Aeolian/Fleeting, Armor Crush/Forked, AoE, Throwing Daggers, and perhaps Huraijin.

(5 buttons saved, or 6 if Huraijin's functionality were instead consolidated by just changing Armor Crush's 30s Huton refresh to a 30s Huton gain, as an additional effect instead of a combo effect, and increasing its base potency -- siphoned from combo bonus.)

Samurai would need 8 GCD keys: Iaijutsu (Tsubame), Gekko, Kasha, Yukikaze, Oka, Mangetsu, Enpi, Ikishoten -> Namikiri.

(6 buttons saved)

Monk would need 12 GCD keys, its 9 rotationals, SSS, Anatman (ugh), Perfect Balance -> Masterful Blitz.

(1 button saved.)

PLD would need 8 GCD keys: Goring, Royal/Atonement, AoE, Lob, Circle, Shock, Clemency, and Requiescat -> Confiteor (combo).

(4 buttons saved.)

WAR would need 6 GCD keys: Eye, Path, AoE, Tomahawk, Fell Cleave / Inner Chaos, Decimate / Chaotic Cyclone.

(3 buttons saved.)

DRK would need 5 GCD keys: Souleater, AoE, Unmend, Bloodspiller, Quietus.

(3 buttons saved.)

GNB would need 8 GCD keys: Solid Barrel, Gnashing Fang, AoE, Lightning Shot, Burst Strike, Fated Circle, Sonic Break, Double Down.

(2 buttons saved.)

Similarly, BLM could consolidate the mutually or only sequentially usable Ley Lines and Between the Lines, Flare and Freeze, and Fire IV and Blizzard IV.

(3 buttons saved.)

Etc., etc.
