Here’s the thing, what do designers do if they can’t nerf the overpreforming stuff but still need to make challanging content? They design said content around the most powerful weapons so that it stays challanging. This is what happened in BL2 with all of the raidbosses, especially Verocious the invincible as he was specifically designed to see if GB could create a raid boss the community couldn’t defeat within a day.
However, doing this will bury the non-meta weapons(as well as action skills and pets) even more.
The idea that PVE games don’t need balancing is honestly baffling. If you dont want to be challenged, there are 3 lesser Mayhem levels, normal mode, and an easy mode that you can obliterate all who stand before you in. You shouldn’t be forced to use weak guns in order to have a challenge on a mode that was specifically advertised as being for optimized builds only! The fact that the Lob can get me through two slaughtershaft rounds with a total of 10% gun damage in my build(wich is 100% utility and defense) , a shocerator(not even using the clone mind you) COM, and an icebreaker relic(the only source of damage in the build)… thats stupid. Currently the only reason not to run the Lob is that it has a short range, but for most bosses thats not an issue as you are forced into an arena where you have to be in close range.
If you want mindless fun, play on non-mayhem normal mode. Dont force the idea that the game should be laughably easy even on the hardest difficulty on everyone else.
