Not saying we should steal the idea, but Fallout’s S.P.E.C.I.A.L. system is very unique, original, and character defining for an RPG.
Or Wasteland’s C.L.A.S.S.I.C (And yeah, Wasteland was somehow the game which gave birth to Fallout ^^) …
But Back to Topic: Stats should be Max Life, Max Stamina, Max Energy and Bonuses in % for each Weapon-Type or other equivalent (like crafting branches, …)
The Rest of the “stats” should come through items you had crafted, like base damage or regen of stamina/health/energy. I don’t want to have a evasion, but a skill for blocking, so no stats for that 
I would like a kind of stats, except that instead of gaining stats by leveling I would like a large skill tree that includes many passive and active skills that you can level up through use. The mastery of skills and the armor you wear would be what stats you have.
