Now allow me to interject with my own troubles.
Please don't shoot me, but I've come from WoW where I have a total of about 20 Keybinds.
My preferred Keybinds are 1,2,3,4,5,Q,E,R,C Alt-1, Alt-2, Alt-3, Alt-4, Alt-5.
I've got piano-player hands (Very long fingers) and so it's quite uncomfortable hitting any other keys (Or doing so without hitting the wrong key. I'm notorious for hitting Windows key instead of alt)
That being said, theoretically speaking, which would be the easiest keys to start working into my current keybind set up? (My mouse is, sadly, very basic)
