World of Warcraft there are talent points which give customization. But what about stat customization!?!?!?

If they made it to where you could customize your stats that would make World of Warcraft more interesting because tanks could concentrate more on there primary stat (stamina). DPS on there primary stats which would be (strength and/or agility stamina). Mages, Warlocks,(elemental, restoration) shammys and (restoration, boomkin, moonkin,etc...) druids would be able to go longer without mana breaks because they could increase there (spirit, intellect). it would make things alot more player friendly in my opinion what about you?
