Thank you
Actually I feared the answer would be like that...
Doing it with custom quickslot bars is completely out of question atm because the whole point in doing it is to have different skills mapped to the same keybindings with different layouts.
I don't really want to use my mouse to use the skills.
Maybe as you said sometime in the future then when we will be able either to access the original Turbine quickslots or to assign keybindings to custom quickslots.
