I just started using AR's before the de-buff, had brand new Suros, Hardlight, Vanquisher, Up For Anything, and a couple others I was starting to try out - normally use scout/HC All getting dusty after the buff - went from being an ok choice even for players like me that prefer single shot type primaries to almost useless unless you were really good with AR's already. Some can still make it work, now it's not worth the effort to try and get to that level - my hardlight used to be able to mow down packs of enemies, now it seems to tickle a few of them to death and then I'm stuck mopping up the rest CQC style. Speaking of AR's - A simple buff isn't going to fix that bad (insert long string of unflattering comments here) joke of a raid exotic known as Nechrochasm
