Not really... Seriously, try challenge mode go solo it and tell me how that goes. It's a simple simple matter to stunlock enemies using skills like the flash bang mod on the sticky grenade or, and this is my personal favorite, the smoke mod on seeker mine. But even with a literal 150,000 weapon dps most of the enemies are just large bullet sponges that don't drop. Don't act like everyone is incompetent. I've got two seperate gear sets, one that favors firearms and the other that favors raw skill power for quicker cooldown of the aforementioned skills. I also have all the weapon blueprints out because of the broken Phoenix coin drop rate*fixed*. I've crafted my items properly and even take advantage of the occasional bug like the Midas sub machine gun perk *which they have since patched* and the mask talent that restores 2% health per second while under a status ailment, which persists indefinitely after being affected by one.
