Feature Request: Customize Attribute Point Gain Rate for OoE

[EliteSoba]

I'm working with the understanding that the max 65535 attribute points leads to a 200% increase in attack power for that attribute (so ~327 points per percent). Done a few runs with the "Gain Attribute Points faster" option both on and off, and the fast feels too fast while the normal one is a tad tedious at times (especially because the growth rate can get eclipsed by #145). Not sure if I'd prefer choosing a fixed value or a range. Would be cool if it used the same slider as the PoR mastery one, but unfortunately those ranges seem too incompatible.

For reference, I feel like 4 would probably be my ideal "harder difficulty" multiplier, with 2-5 being a somewhat reasonable random range
