Make it possible to unequip your pet
Make it possible to skip cutscenes Atleast make it possible after you finished the game already.
Get rid of all penalties on Mayhem modes These penalties are not making me change my build, and I don’t want to. I just want the enemies to be stronger on all aspects equally. If you want to make Mayhem modes more interesting/different, you have to give certain enemies extra buffs or immunity, but global penalties are annoying.
Rare statistic spikes It would be cool if there could be super rare statistic spikes in the end-game. Everything seems to be capped without any small variations. Right now it’s always 45% max critical etc.
Improved Rooms The customization of the rooms is super bare minimum. They added some hooks and that’s it. Room skins, and placing decoration that can drop from enemies would be a big improvement.
Infinity gun variations Some variations on the infinity pistol
Bigger bank My bank is full with legendaries, everytime I find a new legendary I need to drop another one, really annoying when you like collecting them
PvP Arena A gladiator style level with a crowd and a broadcaster similar to the Killavolt mission in which you can choose to fight 1vs1, 2vs2 and 3vs1. And before the match players can place a small bet on who they think would win.
