On my server I can routinely make 100 of these every couple days and sell them for 5 g each. Since they are used by many raiding dps. I spend about 2.5 to make each one (with out any procs ). With procs I am spending about 2.25 ish each pot.
I sell them in stacks of 5 and list them about 1 hour before common raid times. This ensures I am the lowest price on the ah. I also use a 12 or 24 hour auction so I can save them to relist on the next major raid night on my server.
