I just want the 1-2-3 combos to stacking on one button be an option in PVE. Lots pf rotation skills can be stacked like that.

Why doesn't Fire and Ice 3 convert into Fire and Ice 4 when Enochian is triggered? Why doesn't Hypercharge just turn into Heatblast when hit? Why don't the lowest healing spells like Cure 1 and Physic just turn into the updated spells of Cure 2 and Adloquiom?

I'm sure EVERY job has examples that could use the option to stack skills.

It makes controller play way more daunting for some jobs due to button bloat and PVP added a solution years ago that just hasn't been moved over to PVE. (Scholar in particular is a disaster on controller from the sheer quantity of skills given to a capped player.)
