I disagree. I think after the previous tweaks to monster generation, the current balance feels just right. Some previous versions where practically every monster in the late-game dungeons was an ancient dragon, titan, moloch, etc. were just ridiculous, and the game got repetitive. Now you find plenty of high-level monsters but with a healthy mix of variety and I think it's just fine.

I recall making a similar RFE quite a while ago and it was similarly rejected.
I still think there's a *bit* too much low level monsters generated in high DL areas.
Not saying there shouldn't be any, just less than now.

I wouldn't mind tweaking the monster distribution again a little, pushing it a little more towards high-DL monsters. We've had some releases where it was too much, but that doesn't mean we're at the perfect balance now.

I think the distribution is fine at the moment. Unless a large number of high level monsters get added to the game, skewing the distribution will make it that you just see a lot of the same monsters over and over and over again. There's one version--pre18 or so maybe?--where things were skewed quite extreme in this direction... on one level, every other monster would be fire giant; the next, every other monster would be a berserker emperor.

[edit]Not a bug, anyway.
