Better Leveling Through Chemistry

The origins of the phrase "Better Living Through Chemistry" go back much, much further than current pop culture.

It's actually a variant on the DuPont slogan "Better Things for Better Living...Through Chemistry" which they adopted in 1935.

Doing the math, you would need at least 4 banker toons to store the raw mats. Without adding in the procs and everything else, guild bonuses, etc. Here is what I came up with. (Not including the Crystal Vials since you can easily purchase those from a vendor).

Flask of the Winds: 8 Volatile Life 8 Azshara's Veil 8 Whiptail
Flask of Titanic Strength: 8 Volatile Life 8 Cinderbloom 8 Whiptail
Flask of Draconic Mind: 8 Volatile Life 8 Azshara's Veil 8 Twilight Jasmine
Flask of Flowing Water: 8 Volatile Life 8 Stormvine 8 Heartblossom
Flask of Steelskin: 8 Volatile Life 8 Cinderbloom 8 Twilight Jasmine

3000 Flasks needed to be made. 600 of each flask to be made for the 3000 Mix Master achievement. Total for Volatile Life is divided by the amount of a full stack which is 200. Totals for herbs is divided by the amount of a full stack which is 20.

Volatile Life: 40x600=24000 (120 stacks)
Azshara's Veil: 16x600=9600 (480 stacks)
Cinderbloom: 16x600=9600 (480 stacks)
Stormvine: 8x600=4800 (240 stacks)
Heartblossom:8x600=4800 (240 stacks)
Whiptail: 16x600=9600 (480 stacks)
Twilight Jasmine: 16x600=9600 (480 stacks)

A total of 2520 slots is needed to store the raw mats for the flasks.

Each guild bank tab as 98 slots in it. With a banker guild, only 6 tabs can be purchased (unless you and some friends want to share it and level it up). That brings the total to 588 slots.
If you can manage to gather up 7 Hyjal Expedition Bags (thats 36 slots each), thats an extra 252 slots, along with the 28 slots for your toon's personal bank.

So, lets see here:
588+252+28=868

A total of 868 slots on one toon! So therefore, you need 3 banker toons to store all the raw mats you will need to get this achievement.

3000/868=2.9
868x3=2604

So you will need an extra one to carry the last 580 slots.

Happy mixing!

I tested this after reading your post. Making the [item=62288] did not count towards the achievement. Consuming flasks from the cauldron once it has been dropped also does nothing.
