PSA: No, OP 10 is NOT balanced
Ever since Garnet Anarchist uploaded his "OP 10 with no uniques" challenge run, I feel like the consensus on OP 10 has been shifting to where people think it's actually not unbalanced. It's just properly challenging.
And to those people I have to say: Stop it, get some help.
Garnet Anarchist is not representative of your average Borderlands player, or even your average hardcore Borderlands player. He's a turbo autist who plays Borderlands for a living. And even in that challenge run that gaslit you into thinking OP 10 isn't that bad, he had to cheese the tutorial boss by breaking its AI.
