Leveling in RP would be training. I mean seriously, are all warriors the same? No, some are much stronger, faster, and smarter than others. Some are skinny cowards. Which one are you? It partly depends on how much you train (level). When it really comes down to it, you're weak because you want to be. I'm sure if you spend some time to go out and (train) you will see things in a new way. I'd say that's more fair than restricting everybody to a set amount of hp, speed, blah, blah.
Btw, what about fat sorcerers and whatnot, you know? Let's not discriminate. So, a warrior in heavy armor might still be faster.
