Combo Action Button

[Rongway]

Now riddle me this. After using Impulse Drive and enabling use of Disembowel, for what reason does Impulse Drive remain on my bars?
I will never consider using Impulse Drive twice in a row. That would be a straight dps loss, not to mention screw with upkeep of BOTD. There is literally zero purpose to Impulse Drive once I've cast it and moved up the chain. All it does is consume a hotkey and button space.

But the point is you can make the wrong decision and use it twice in a row, and indeed some people do--especially when they're still learning a new job.

This is not like conditional or mutually exclusive abilities, which you are literally unable to use under the wrong conditions.

Example: You cannot use Between the Lines unless Ley Lines is active. You cannot use Ley Lines while Between the Lines is usable, because Between the Lines is only usable when Ley Lines is already active. Therefore these two actions should be the same button. This is not like advancing a combo, where it's possible to abort or reset the combo for whatever (usually bad) reason.

So your argument against the idea is … To keep it unchanged because new people make mistakes? There are plenty of mistakes that can be made naturally outside of the basic combo.

I'm saying you can't compare combos to conditional or mutually exclusive abilities. They're not in the same boat. Having separate hotbar slots for conditional or mutually exclusive abilities is inarguably a waste, because there's no situation in which you can use the two at the same time. Having separate hotbar slots for weaponskills in a skillchain is fine, as it lets you make the choice to use them out of order, whether that is the wrong choice (in most cases) or the right one (typically MCH, SAM, MNK mechanics).
