Need a math geek. (MNK)

It's an 18% increase in potency over that span either way. I of course assumed TwS and DK were both active for every hit since they should be. The biggest reason why this would be a dps loss is not because of this particular moment, but because of a later moment, when you lose greased lightning. If you - at any point - drop GL3 due to mechanics, and you burned your PB on this, you're stuck spending a far greater time ramping up than if you GL off the bat. (That is - 7 gcds at not-gl3 as opposed to 3)

You forgot autoattacks. They're no small portion of a monk's DPS, and losing out on the 30% damage and 15% attack speed on them even for a couple of seconds can be impactful.
