Theorycraft already started on it, in a worst case scenario it was around a 1.6% Dps loss in patchwerk which is completely negligible with MG still being the top talent on that row for ST. This also has the effect of just straight up buffing afflictions multi-target potential since that dmg was moved out of MG and back into dots, which means more damage in more situations.
If you have evidence to the contrary I'd be down to see it, but everything I've seen disagrees with your notion.
