So... you guys added this nice little thing that is the Combo PvP Button. For example, as a Paladin, I get two of them:

Rage of Halone Combo, and Royal Authority Combo.

This combines 5 buttons into 2.

Could you perhaps allow us to make these sort of buttons ourselves for use outside of PvP? It would go a long way to relieving hotbar clutter, and make rotations a lot easier. Instead of having separate buttons for Fast Blade, Riot Blade, Savage Blade, Rage of Halone and Royal Authority, we could just have the 2 buttons that automatically switch.

Let us set up the buttons so that they switch automatically like they do in PvP and if an action is not available at current level, then the button just automatically skips it and goes back to the first ability (for example, if I am in a dungeon <Lv60, the Royal Authority Combo will simply Fast Blade -> Riot Blade -> Skip RA and go back to Fast Blade).

This seems like so much a better way to do this, and the system is already there (but AFAIK, you can only use it in PvP).

Allowing us to set up our own combo buttons would be interesting and would make gameplay a lot more smooth, and unlike macros, it would allow us to choose the timing of each ability in succession instead of them automatically attempting to fire regardless of whether or not it is even possible or desirable.
