Many high end tailoring patterns require the bind on pickup Primal Might, a component only gathered in instances.
The big chance for tailoring is three specializations in the expansion:
●Spellfire Tailoring: Gives access to Fire/Arcane damage oriented cloth patterns. Gives a chance to receive multiple Spellcloths per combine.
●Shadoweave Tailoring: Gives access to Fire/Frost damage oriented cloth patterns. Gives a chance to receive multiple Shadowcloths per combine.
●Mooncloth Tailoring: Gives access to Heal/Mana regen oriented cloth patterns. Gives a chance to receive multiple Primal Mooncloths per combine.
Each specialization gets access to a new bag pattern. Spellfire tailors get a 28 slot enchanting bag, shadoweave gets a 28 slot shard bag. Mooncloth tailors get a popular one, a 20 slot generic bag. Some high level Tailoring Patterns:
