Its a bigger increase than most people realize.
I don't think anyone is denying the fact that it will increase healing. Because it already does. It is the ramp up time. Even if it is just the judge, and you don't crit your HS, you are twiddling.
and a 290k DL sounds nice and all but how much of that will now transfer to OH. Granted you are going to get your IH shield off of it but it is not like our DL is not already sufficient.
