Since I don't have access to the beta and wowhead/wowdb are fairly limited, is there any point now to having multiple Transmutation Master Alchemists? I'm looking towards getting all my professions done before WoD and this is what I had planned:

Paladin: Engi / Alch
Warlock: Alch / Insc
Rogue: LW / Alch
Mage: Tail / Ench
Priest: Alch / Insc
Hunter: Min / Insc
Warrior: BS / Insc
DK: JC/ Insc
Sham: Alch / Insc
Monk : Alch / Insc
Druid : Herb / Skin

Now, seeing as Alchemical Catalyst isn't made via transmutation, least not that I can find, it would suggest that Transmutation Mastery is lacking. I know the Catalyst is used in alot but is it still worth having multiple Alchemists or does the amount you get from one T3 garrison as well as daily use provide enough that many isn't required?
