I've been considering, of course, a paradigm shift, but... long story short, at the end of the day, it's still a compromise that won't allow too much experiments and / or flexibility. Also, the best combo keys (I use these A LOT), must be in a nearby area on the keyboard, for the left hand. For example, I use: • F - for basic skill• SHIFT + F - for heavy attacks• SHIFT + R - for reinforcing / reloading / heavy buff or enhancement skills (reminiscent from reloading in FPS games)• G - for shield / defence• SHIFT + 3 - small heal / heal 1• SHIFT + 4 = large heal / heal 2• SHIFT + SPACE - special action• SHIFT + G - defensive skill (major)• C - stun / enable skill that has similar function• Q - weapon switch• 1 and 2 - ranged attack with utility skill (summon illusion, summon spirit weapon, etc.)• etc. Meaning: the keybinds for skills are mainly concentrated in a very small area on the keyboard, around the left hand and the basic movement key set (W, S, A, D) for increased efficiency (speed, much more practical). I find the "5" key already too far to reach so... no point in going to the example given 7. ;) I don't see anything better than that that small tick in options for "Use different keybinds for characters".
