What, in this example, would denote that this character "tough"? The ability to carry more stuff? The slight chance to deal more consistent damage in melee? Toughness is a function of Constitution.When it was first suggested, I felt that removing ASIs from races would make them less diverse, but seeing them presented this way... I really like it. I can always make my Giff have a bump in strength and constitution if I want to play up that big ol' hippo, or I can put it in intelligence and wisdom for my wizened old (but still tough!) wise-guy hippo.
