if you bring it backyou are just going to mess up balance and i dont think the devs want to deal with the possibility that some tank might have 150vit and another have 250vit.
A whm would ignore int all together and go full mnd with tiny bit of pie, sounds good but it becomes over powered.
I think a little freedom such as the skills we get from guilds or merit type system be ok, but being able to pound in 50-100 points into 1 stat is dumb, makes gear pointless.
