You know what BL 2 and Diablo II have in common? Multiplayer matches scale up the number of enemies and the worth of the loot depending on how many you have in a game instance.
It didn't take very long for players to learn the Player8 command (may be splling it wrong) in console had you facing foes and reaping the bennies as if a full team of eight players was in there.
If there isn't a command like that in BLCMM, Might I suggest it be crafted? I like singleplayer, big challenge, and even bigger reward. (Not that I'm beyond using a trainer to leap like the frigging Hulk, but it's not like Goliaths don't do that, right?)
Any rate, that's the suggestion.
