This is true too, but I believe it might make things interesting to add guns some other qualities than damage and range. Otherwise it'd end up being just sg version of minigun.
SG version of minigun, yes, but what's so bad about that? Less range, less damage on range, though has the advantage in close quarters with higher DPS, lower requirements, less shots per magazine than minigun, less ap needed to shoot, both would need BRD to work effectively and in the end SG has a great weapon to use, p90, ordinary minigun has it's place, so i don't see what's the problem.
Improved flamer is not available, what Solar did now was just stupid as always. He introduces new pyromaniac perk, that is useless without improved flamer witch he made almost unavailable, as well flamers in general need a range boost of few hexes.
Shit, changing shots per magazine, damage etc. etc. in server files is like the easiest thing you can do, and nothing is done, Solar rather buff some avenger minigun, lazer rifle well used weapons already, instead of trying to do something with SG/Unused weapons.
