/sigh.

Fine. Simulation incoming.

Actually, Glyph of Flame Shock is going to be pretty critical when you get your 4pc bonus and are generating lightning shield charges at twice the normal rate. The ~300 dps difference is assuming a no-gimmick setup and you know how to manage your shocks properly.

You said " until he gets the shado-pan trinket." That trinket is a on-use crit buff trinket. The preceding comment was about getting FRG until he could get said Shado-Pan trinket.

My guide says it is a rough estimate, and it even has "rough" in bold. Perhaps it is you who fails at reading.

Saying that 2.01 for Haste and 2.00 for Mastery makes Haste better means that you fail to understand statistical probability and error margins (and also pulled those numbers out of thin air, because Elemental does not have weights that high for either of those stats)

Here is the sim, using my current gear.

As you can see, Mastery is at 1.18 with Haste at 1.17. By your logic this must mean Mastery > Haste, but the error value of 0.05 means that Mastery is really 1.13-1.23 vs Haste with 1.12-1.22 (if it's a percentage the value ranges will be different, but still over-lap). Obviously there's no clear way to say that one is better than the other, unlike with either vs Crit, which is at best 1.12, or equal to the worst possible values for Haste & Mastery.
