Get Outta Town!
I'm not disagreeing with you, but when you compare 1 or 2 guys using a Fighting Lion farming for mountaintop or whatever, to the 10 other guardians spamming 1 shot head shots across the map with a Jade Rabbit it's really not that bad. It's just an opportunity for people to farm what they wanna farm at an easier and faster rate, whether that be the MT, the Randy's or even a catalyst. Blacklisting guns seems pretty extreme, the game warns you preemptively that firearms do significantly more damage, so the fact that an exotic grenade launcher that fires explosive rounds 1 shots people, is really no surprise at all. I agree that the ammo count especially per pickup is a tad OTT but other than that I see no errors.
