I just made a large spreadsheet to help me out when making profit calculations when it comes to enchanting scrolls and I thought I might aswell share it here!
I took nearly all cataclysm enchants from here, made some short notes on how to get them, what mats are requierd and ran them through a formula containing the current prices on the AH to see how large profit there is to be made per scroll.
Here's a link to google document containing the spreadsheet:
Enchanting Scrolls Spreadsheet
It currently contains info relevant to my server as of the date of posting, just replace all the fields coloured in green with your relevant information and it should calculate the profit for that scroll(hopefully).
If you find any errors, please notify me and I'll see if I can't fix it!
