Built a testbed PTR sheet. I receive about a 10% overall DPS increase with the present changes (I did not model an increase in TV from 235% to 270% - until confirmed otherwise I think someone read a tooltip and got excited).
Priority became:
Inquisition > TV > Exo > HoW > CS > Judge > HW > Cons
In short, the only change is TV jumps up to second place above HoW and Exo. It still appears advantageous to use Zealotry and AW together - should be fairly clean. TV when engaging Zeal+AW, then cycle through HoW, CS, TV, Filler. Occasionally Exo would step in, but it either takes the filler spot or makes that sequence HoW, Exo, CS, TV.
For my gear CS Glyph slightly edges out Exo Glyph. It's possible, even probable, this isn't the case for all gear (such as weapon DPS lagging behind stats). Difference for me is about 0.2% DPS, so it's really marginal either direction and easily folds into RNG fluctuation.
Going back to a +3% crit meta looks to be about a 1% upgrade. Swapping the Crit Rating to some (presently unknown to me) value of Str should also boost the value.
Mastery maps smoothly. Slots just a shade under Expertise in value. Since it became better it also boosts Hit and Expertise a fraction (a miss/dodge means no benefit from Mastery).
In my PTRfaker sheet roughly:
| Stat | Value |
|---|
| Str | 1 |
| Hit | .296 |
| Exp | .190 |
| Mastery | .184 |
| Crit | .130 |
| Haste | .128 |
Same format as presently used for apples and apples - not putting DPS per stat to avoid comparison confusion.
Haste is probably about equal with crit - its model remains less than beautiful because of the AoW and DivPurp procs. Mastery has more than doubled in value and is now about 40% ahead of Crit/Haste. It shouldn't appreciably change gemming - still one orange/purple for 20+ Str or two for 30+. Gemming for Mastery bonus or a single-gem 10 Str should still be a minor loss. Str is simply still that far ahead.
Personal assessment - Mastery is too powerful because it goes from notably behind crit/haste to notably ahead. It probably needs a smaller coefficient (1.75% to 2.25% per 1 Mastery) to balance about equal with Crit/Haste. Str blowing away all stats is bad design, but it would take vast rework to correct at this stage, Blizzard is obviously swallowing any bad taste and proceeding. Everything else should be designed to be roughly equal so juggling is more dynamic and not kneejerk "Reforge for X". Since Mastery is getting the facelift, it's the perfect time to peg it to roughly equate the other two stats.
Chippy - fair enough. DPS Increase per Stat will be put in the OP, but don't expect it reveal any root difference between the spreadsheets functionality. If it did, I'd already have dug in and corrected my flaw (or advised Redcape if I thought I saw one in his work). The difference is, at root based on scope and scale of simulation.
Finally - minor bugfix version of my spreadsheet is up with same link.
