Does depend on the class, but here is my setup. Q-W-E-R-T-S-F-G-X-C-V-1-2-3-4-5. I then use the shift and ctrl modifier with the same set up. That leaves me with a total of 48 keybinds for my stuff. More than plenty for any class.
It’s really not that bad as you describe OP. Plus my hands are small.
