Combo Action Button

Then stop assuming and start thinking, maybe it will help you realize that Blizzard IV and Fire IV are as mutually exclusive as Inner Beast/Fell Cleave and Steel Cyclone/Decimate.
Therefore, there is literally no good reason for them to require two slots in your hotbars.

I am thinking. There's literally no reason why Fire IV and Blizzard IV need to be consolidated onto one button because you find pressing either one too much work apparently when you're pressing Fire IV more than you're pressing Blizzard IV anyways to begin with.

I bet you're a Black Mage that uses Freeze too.
