I mean, that’s great for you and your group, but you literally said “experienced DMs shouldn’t be running balanced encounters.” Well, I’m here to tell you, balanced encounters work perfectly fine, if you run enough of them, as the rules say to do.
Please don’t call my games boring when you’ve never even played in them. This is extremely rude, and I am actually insulted, which is pretty rare for me.
It’s also unsurprisingly (and explicitly intentionally) good at making players feel both powerful and meaningfully challenged when you do run the number of balanced encounters the rules recommend.
