let me say I am cool with sacred cow becoming hamburger... if they changed/did away with str/dex/con/int/wis/cha I would give it a try... I don't know if it would feel the same thoughI mean, yeah, at this point it is questionable whether ability scores serve a reasonable purpose. But as long as they exist, I want them to actually represent something; if they don't, I have no need for them.
Pre 4e my group had gone cold on D&D (and it was a much larger group at the time) so we branched out tried WoD, CoC, Deadlands even for fantasy games... but as much as we didn't want to play 3e anymore nothing quite got teh itch scratched... Now we splintered on 4e/Pathfinder/giving up RP right at the PF/4e age... and we somewhat got a bit back for 5e, and I don't know if such a large swing would get us all MORE into D&D or less...
