What if you created a f2p model where you have a certain # of stat points and certain # of skill points you can use. With the skill points you can only use them on combat oriented skills. So if you wanted to you could create a badass mage, but you'll be super squishy and maybe not so great at wielding a melee weapon because your stats/skills are limited. You also prevent people from creating free crafting or gathering alts. The only free characters will be for PVP. I'd be down to jack around in the game, but I'm not going to be invested enough to make paying for it worth it. Why not have a f2p model for some population boost while not losing any paid revenue to people who are invested in the game? And giving a clear upper hand to people who pay for an account, but not totally limiting the f2p to be decent in combat.
