I know the feeling Why do I need at appear as more than one player? I’m only one person.
Specialisations that are levelled in line with feats would also get past the problem we now have - that at best a character can only do one thing.
If you smash a lot of rocks and bake a lot of pie, then you’ll end up being a first class miner and chef. This should allow much longer term players to become proficient with a few specialities in line with their play style and potentially even allow the really hard core OCD players to grind out every little detail - which may take years.
Regardless, you’re continuously rewarded for playing your way.
