Look here, INTELLIGENCE WILL AFFECT ENERGY WEAPONS! IT WILL ALSO HAVE A PART IN THE OTHER COMBAT SKILLS JUST NOT AS BIG OF ONE!! do you get it now?
Its impossible to do a powerbuild like this "10 PE 10 AGI 10 ST and 10 Luck" NOW - why? INT would be 1 or little and not enough for getting high % of skill
Wait like make energy weapon base value increased by int?Well not that it gonna change anything but first few levels.
To discuss this thread you'd need to present more formulas. I still do think its impossible to implement (number of skills that you proposed is less than original)
