Tailoring, why perks sucks for melee?

So i levelled Tailoring on my Monk for the [Master of All] achievement since i don't play clothies and was pretty disapointed in the perks.

I get its usually a profession geared towards casters, but take Blacksmithing for example that should be geared toward plate wearers, is equally good for everyone.

There's no cheap leg enchants for melees in tailoring, no cloak enchant for tanking and tbh 4k AP is inferior to any agility bonus every other production professions offer. Kinda bumming.

I'd drop it to level something else but i'm an achievement hunter and would hate if they came up with a "master of all" next expansion >.<. I just don't get why they make one profession in particular totally suck for most classes in the game.
