It's clear that most IR3 presets got trashed by the patch. ATAC and CSG come to mind
Now, this isn't the first time it happens - but it usually was due to clearly OP weapons being brought back in line, which isn't quite the case here
I don't know what LO's plans are but as a bandaid fix I guess some ARMAS presets could have IR3 swapped out for IR1, as they work out what they want to do with them?
Not the best thing but it should help a little bit for the time being
