Soooo, if I’m correct,

DRk combos would be like: 111 111 111. 2 when you have to bloodspiller/quietus.
WAR would be 112 111 111 111 112. 3 when you have to Fell cleave and 4 when you have to Primal Rend.
PLD would be 111 222 4 111 222 4 111 222 4 333 (where 2 is Ato, 4 HS, 3 Confiteor combo)
GNB would be 111 2(5)2(5)2(5) (2(5) Continuation combo)

DRG would be 11111 22222
MCH would be 111 111 1111
And so on…

Really I’m not getting the point how condensing a simple 123 into a 111 could be better.
I main the last most busy jobs left in the game (DRK/GNB DRG AST) and there isn’t a real “button bloat” problem, just a skill issues problem (or ping issues that would be more understandable tbh).
If there are more OGCDs/GCDs in the game, it could be a better thing for sure but now? Nah, I don’t think it’s a good idea with these skills we have now.
Just my opinion tho.
