Still seems like you have to reposition your hand a bit, but looks better than using the F keys. I’ll have to give it a try.
I only have Alt modifiers for keys 1, 2, 3, Q, W, E, A, S, D. My hands aren’t very big so any keys beyond those is too awkward.
Yes, I also only use keys on the left side. Those keys should be plenty for what’s left of the unbound abilities.
I think I have the same mouse but I’ve switched to the side that has two buttons (the interchangeable Razer Naga).
I use WASD for movement. Q and E for mount and the movement skill.
1-5 are my attack skills and the 3 mouse buttons are for skills I use off CD (Sera, Avenging wrath and essence).
I like this setup as I don’t need to check my skill bar often as there’s few classes than need you to press more than 10 buttons often. Shimmer on my mage feels particularly nice to use as my mouse middle button.
