*I COMAND YOU TO RISE FROM THE DEAD MY OLD TOPIC*
ehm

I just thought about it recently ...
And maybe i find alternative way.
How about allowing certain classes to use their alternative ability modifier as yet another bonus to roll?
Like:
Roll Nature + Proficiency + (Int -1mod) + Bless (1d4) + (Druid/Ranger Wisdom +4mod)
OR
Roll Intimidation + Proficiency + (Cha -1mod) + Bless (1d4) + (Barbarian Strength +4mod)
That way we would be able to play our characters properly ... still potentialy able to make rolls that make sence for certain classes a little easier than others with no relation to that subject, yet not so easy as dedicated characters, since we still have there that -1 from our dumped stat.
