The current math works out to the following:
1 TR to 1 Silver with Blizzard converting it for you. Which takes 0 minutes.
When doing it yourself and spending 10-15 minutes (30-40k TR):
1 TR to 45 silver.
So you are getting a big increase in gold if you can ‘‘find’’ the time the coming days to convert the TR into AP gear with the above mentioned macro by Psohly.
I just finished up doing my characters, and took me 30ish minutes for 90k TR or so.
To Someonelse : I am sure that today where the price of BfA mats are at their lowest with the end of the expansion, the money you’ll get from selling the mats from scrapping is less than the 82 gold from selling… plus taking the time to scrap them then selling at the AH takes more time (checking price, listing, relisting, etc.) than simply selling to a vendor.
To Damae : thanks for the figure - 30 mins for treating 90k TR (i.e. a net gain of 41 000 gold) seems very good. There are not many of us who know ways to make more than 80 000 gold per hour, by far (I sure don’t).
