I want the world to feel real, not custom-tailored to our characters. I want the characters we bring and the decisions we make to matter. Changing the adventure / world to match our characters' capabilities invalidates our choices in making / bringing those characters in the first place. And thus is red flag for me for the players' choices mattering. Consider it a subtle form of railroading.
But.
If the DM knows ahead of time that most of the foes that the party will face for the next 7 levels are elemental, undead, constructs, and oozes, and somebody brings a DPS SA rogue to the table, it's equally bad form not to mention that their character may struggle, and they might want to consider making a different choice.
I hope that clarified my position on the matter.
