The Best in Bags feature recommends I take the Meteorite Whetstone over
Incisor Fragment (yeah, I desperately need new trinkets). I would have thought the 148AP would be better than the 74Crit, especially with the On Use 20 sec - 291AP (v. 10 sec. 444 Haste).
I trust the calculations. There is no way to really tell the difference between those two trinkets without some sort of mathematical model - that is how blizz designed the game.
Also, 1% theoretical dps is so small that you won’t be able to feel a difference in-game anyway. I personally just go with whatever the robot picks for convenience.
