As many people out there I dont like the actual physical system, because it just doesn't make any sens to me... on the other hand having a metaclass that reflects how much you play is something I would love to keep in the game.

by lvling up your "adventurer" (I admit that's not the classiest name outthere...), you would basicaly gain skill that makes your life easier, but would not have any effect on your stats.

As an experienced adventurer, you know your way around the world hence you go faster, regen faster anima and so on. hl adventure would have an advantage compare to casuals, but this would not be an outragous one.

In my opinion, it just make more sens than the old physical system.
