1) Cauldron of Battle takes 10,000 flasks having been made
2) Flasks cost about 300g in mats on current auction house prices
3) This requires 10,000 x 300g = 3,000,000g
4) 300,000g = $1330 USD
5) Need ten times that, aka $13,300 USD

So we only need 3000 of us to pitch in 1000 gold!

Sure Chops is aware but the achievement is being (or has been?) lowered to 1,000 flasks.

yeah they lowered it, were at about 270ish flasks
