Seeing as how there have been multiple questions asked in the forums lately about things that are specifically tracked here, it's time to make this thread visible again!
Things included in the spreadsheet linked
1. Advice & Suggestions for doing daily writs, refining materials, leveling alts, add-ons. What affects drop rates of gold materials, surveys, and master writs.
2. A color-coded sheet showing survey reset paths (what I've found to be the shortest, but if you find a shorter one, please share!)
3. Results of refining millions of materials both pre- and post- Meticulous Disassembly being added to the game... yes, it most definitely increases your improvement materials received when refining
4. Detailed results of drops from daily writs with nearly a quarter million writs done total across all 7 crafts! Special jewelry rewards tracking for the 4 grain types you get from those!
5. Writ Rewards and Writ Profits calculated out for both max level writs and level 1 writs (hint 1: do your writs at max level!)
6. Individual refining results for the 4 crafts both pre- and post- Meticulous Disassembly (as well as even pre-Multicraft). (hint 2: refine all at once, save yourself time)
7. Per patch results of drops from daily writs to check for any major changes (there aren't really many)
8. Prices included from the average of the 3 trading guilds I'm in on PC/NA so the value of all the rewards can be continuously updated.
Spreadsheet is regularly updated and kept up to date, even when I go through periods that I don't do as many writs!
