Edit: I changed this to suggestions because no one was able to answer a way to do this.
I think we should be able to use Right Click, like for a skill slot. And middle click too. It doesn’t register in the key bindings. I think it should be possible…
I don’t mind the current menus from right click being another button, it would just really be better for combat if I could charge skills with right click, because I use keyboard (to move) and mouse.
Also, there should be a way to use shift+clicks to make more skills usable by the mouse. Is this possible now, or should we talk about this in the suggestions?
