Given that people have yet to fully try MV burn on anything larger than a UFO, it remains to be seen how bad the "nerf" was.
There's not a lot of people who have SCH at 75, much less with the specific merits to guarantee that they'd even get a good helix off. Then there's the fact that coordinating the usage of the MV JA by multiple people is tricky at best.
Once you land the helix, you have to see/ guess at when a tick has passed and then hit MV all at once... any sort of delay, lag, staggered use screws up the attempt.
Anyways point is SE overreacted I think and even then I still want to see people make the attempt and post results... Even if we can't milk this strategy for a one shot it still might be useful as part of an overall strategy for taking down AV.
