Not to mention the tower fights have the death penalty, if you're comparing it to training day.

They aren't much good for anything aside from EXP and the catalysts, I'd say they're perfectly fine right now.

I have stressed in the past to offer something like Kunai suggested (mostly bumping Chaos' idea) of harder monsters that provided more exp, to reward people who want to grind not by just spam killing as many mobs as possible.

I haven't grinded much in ages though, but as far as I can tell BDPs haven't much changed aside from full-clears being made much easier to keep track of and perform with the QoL changes. Maybe someday we'll see more interesting bosses thrown into those, too.
