So, so, so, so true!
Beyond that, IMHO, 4e is vastly better using its paradigm in terms of describing QUALITATIVE differences between things like mid-heroic "I'm the toughest guy in this neighborhood" characters vs say mid-paragon "I can climb to the top of Death Mountain and beat everyone in the kingdom in a wrestling match." vs mid-epic "I'm the trusted left-hand of Kord!" and drives the fiction to display those differences. I mean, sure, if you want to play a nonsense game of 4e where things have bizarre DCs that make no fictional sense, be my guest, but that is NOT HOW IT WAS DESIGNED. When you are Epic, you do EPIC STUFF, and that has EPIC DCs. If your epic fighter finds a ladder, he just goes up the damned thing, he's a DEMIGOD, he doesn't need to check to see if he can climb a normal ladder!!!!
My feeling is that the 5e-like approach of non-scaling checks is an attempt to make everyone mundane. Its a 'Gygaxianism' that arose long ago in an early phase of D&D where cutting the PCs down to size so that the GM's map and key offered a challenge was the order of the day. I mean, its also a question perhaps of 'naturalism'. I would agree with anyone that said that largely non-scaling checks and fixed DCs were probably, usually, more realistic, but this is a game of magical elves, I don't want realism in my peanut butter, thank you!
