I meant the perk, and let me clarify: it SEEMS to not affect bursts. I've been using combat shotguns for a long time, and I'm pretty sure their burst cost 5 APs BEFORE I took BRoF (or BRoA, whatever. At least it looks funny) and it costs that much now. Could someone please verify?
Either way, not being able to make single shots at 2 APs with 2 handed guns (that is to say, the majority of the really effective weapons) is still a huge blow. Not to mention other senselessly slaughtered perks.
