Normally I just give a grammar warning for something like that, but you've annoyed me with the "LONG TIME POSTER, FIRST TIME READER" comment. Newsflash: we don't give a shit.
Original Post:
Firstly, first time poster long time lurker and English is NOT my first language.
I got one of my alts that is alchemist with the exilir mastery and i'm selling roughly 40-200 flasks day depening on the ammount of cheap herb, this generates quite alot of money for me and is something that i'm thinking of keep doing. With the upcomming 3.2 patch i've stocked up cheap [Regal Forest Emerald] to fill my personal need for epic gems by doing the process 9 [Regal Forest Emerald] ->3 eye of zul -> 1 cardinal ruby. and i got that covered for now. However i'm not sure at how many stacks of forest emeralds (i sell every epic red i get out of it) it will be worth switching into tramsmutation mastery, transmute and then switch back to elixir?
This is what i've come up with so far, assumptions
Master changes costs 300g
A hint to the cardinal ruby price would be the [Bold Scarlet Ruby], at my server it's about 65-70g, i expect the price for epic gems to be 50% higher due higher priced titanium ore, higher honor cost and more emblems needed (was 15 in tbc).
I buy all [Regal Forest Emerald] under 10g that i can get my hands on, in the model for simplicity they ALL cost 10g.
Proccrates for a 2 procc is about 16% with higher proccs neglible for transmutation master, the procc can of course apply on both transmutations. Meaning that the for every 9[Regal Forest Emerald] i get 1.15*1.15 = 1.32 epic red gems.
These assumptions without transmutation mastery would give me atleast about 10g profit per 9 [Regal Forest Emerald]. With transmutation mastery i would create 32% more gems, meaning that i'll make an average profit of atleast 13.2g per 9[Regal Forest Emerald]. Meaning that i will make 3.2g more with the mastery in average per craft. Meaning that it will break even after 300/3.2 * 9 = 844 gems ~ 42 stacks to brake even. With that many stacks needed the proccrate of the transmutation should be as expected.
The problem is that this model does not take the insane first days into account and also assumes that i every [Regal Forest Emerald] costs 10g, how will the prices fluctate? A higher profit per gem will generate less stacks needed to brake even, heck will i even make my moeny back from buying [Regal Forest Emerald] from ah. Will the markets get flooded? if there's 1000 cardinal rubies gems up i'm likely to get into a undercutting war, meaning that i'm likely to sell less or get into an undercutting war.
