I Think they should go WoW style, where by lvl 85 you have 15231 HP and complain that it is low as you are a wizard who does 985dps but can't stunlock because that ability is reserved for warlocks
Yes I'm kidding. The fewer levels the better and the lower the stats numbers & RNG ranges the better as well. They aren't only more meaningfull, they are also numbers anybody can do math with.
