How many skills is too many?

[Daralii]

it's not a select few, it's all melee classes, and tanks. They all use combos, those combos have to be done in a certain order to achieve what you want. It's all rote learning/memory. Even the few classes without set rotations,you need to have memory of every skill and what it does.

Easiest way to save hotbar space with combos would just be to have the option to condense them into one keybind, with only branching combos needing 2+, so a DRK's Souleater combo would be 122 instead of 145 or something.
