Honeslty, I have a hard to believing the listing for the trinkets simply based off the fact that I've simmed myself multiple times using EoT/DMF (upgraded) trinket, EoT/Cosmos (normal since Elegon hates me), Cosmos/DMF (upgraded) and every time EoT/DMF (upgraded) comes out on top by nearly 800 DPS. So where that list is saying normal Cosmos + EoT > EoT + DMF (upgraded) it's the opposite for me by a fair margin.
Shrug, probably just the rest of my gear making it wonky but I feel like that list is off.

MG works the same way with haste as any other DoT does. It only ticks "x" times during the channel, more haste = more ticks during the channel. If you sit between a haste two haste thresholds it's doing nothing for your MG cast, only making it slightly faster for no benefit of DPS (other than the slightest cast difference). Whereas if you are able to attain more mastery/crit and stay at the threshold you desire it's going to be more DPS.
