I feel their entire concept of archetypes is kinda biting them in the ass now because its all the same shit over and over again other than maybe some new perks if they dream them up. Other than some exotics I can think of just a few "new" archetypes they introduced in D2 like the 4 burst pulses, or the new grenade launchers that do the titan thermite nade thing. Bows I guess were cool but only so much you can do with them. So they are stuck in buffing some archetypes and nerfing others to freshen up the meta. There is not really many places they can go other than like I said, new perks, and even then the perks cant even be varied too much anymore because only the dmg type perks will always win out on PC, maybe some others that do the aim assist thing on console are better. Thing is, this is probably one of the better metas weve had, especially in PvP where the most varied of guns can be used to affect. Pulses, ARs (600, 720), fusion rifles, snipes, shot guns, hand cannons (140,150, and even 180s)...
So we have all these god roll weapons weve been keeping throughout the seasons in some off chance that they buff the archetype, at least I have. But I keep going back to the same old 10 or so weapons which really matter in PvE and PvP. I guess you could just use the others but be substantially hampering yourself and your team. But then you dont want to delete any of the old ones in the off chance they buff those damn 450ARs again next season.
