Just because you're lazy doesn't mean someone else is wrong. Leatherworking provides great bonuses and if you want those bonuses well, go out and work for them, bro.
Another thing Blizzard should really make is BoP crafting mats. Something relatively easy to get but something you can't get on the AH... And as for dual professions, make another leveling path viable but cost a lot more mats and time.
That'd be quite awesome.
