Seems like since 0.5.2, MRMs get utterly obliterated by as few as one or two LAMS-equipped vehicles. I've seen MRM20 salvos get completely destroyed by a single stationary Bushwhacker, and this was at less than 500m. Isn't the whole point of MRMs to overwhem AMS?
It seems like there's some bug that causes all missiles to just instantly die if the right one gets shot. I would see a few lasers shoot down a few missiles, then one hit and BAM, like 90-100% of the remainder would just instantly explode. Today, I had the 2x MRM40 Catapult firing at a Raven/Cougar pair on Mirage, and the two of them shot down ALL of the missiles before they had traveled about 200m. Seems pretty weird.
This has happened on every map, too. LRMs don't have this happen to them. I've also seen similar things happen to ATMs, but on a much lesser scale since there's fewer of them at once.
Just thought I'd report it, since it seems for sure like a bug!
