After the Hotfix I think its definitly ok. Maybe a additional buff like the Hotfix is needed, or a change to the interaction between the mgs, but I can't agree with the op. If you have an mg setup and another unit infront and bait the enemys into it both enemys have to retreat. Maybe it should surpress more units at once if they are very near to each other. But really, only small changes or even none.
And most important: Let's wait a bit and let's see how it plays out, with the new patch. The meta is changing, the new commanders will be balanced, everything changes. No need to bring another variable into the equation.
