Combo Action Button

[Sigma-Astra]

I see you still confuse "too many abilities" with "too little slots". I thought I made the difference clear pages ago...

No, replacing Fire IV by Blizzard IV when you have Umbral Ice is not reworking Blizzard IV. Fusing combos on a single slot is not reworking the skill themselves. Replacing Blood Weapon by Blood Price when Grit is active is not reworking those skills.

I'd love to know your definition of the word "change" because fusing two buttons on separate slots and onto a single slot is exactly the literal definition of the word "change". You are changing the way two things used to be into something else. When you're messing with the coding of two individual abilities that function under a third ability (Enochain) while they have to pay attention towards a timer like Umbral Ice and Astral Fire, you still have to re-work the coding and make sure the finalized ability, your single button, functions in the same way that the previous two buttons did.

Now, I don't know whether or not that would be an easy and quick fix, I'm not a game designer or coder, neither are you. But, what you want still requires them to tweak and re-work how certain abilities function with each other fluidly so we don't get an error where Blizzard IV isn't turning into Fire IV when it should be.

One definition is easy. What you can already do by using a macro is not a change. Because yes, if macros didn't have the issue of not queuing properly, you could already do the ability switch from Fire IV to Blizz IV, combo step to the next combo step or Blood Weapon to Blood Price...
Before they did it for Fell Cleave/Inner Beast and Decimate/Steel Cyclone, that's what my WAR Stances macros were created for...
