On the issue of CRs and the "Culture of Balance", I have to disagree. I'm a firm believer in status quo encounters, and CRs are there as a tool for the GM to work out what is an appropriate challenge for a party, to avoid mistakes and TPKing on the first encounter.
Different strokes and all that, I guess, but I can't imagine running or playing in a game where
every encounter was precisely balanced without getting bored.
Some fights should be exactly even, using "roughly 1/4 of the party's resources," sure. Some fights should be easy. Some fights should be a lot harder. And on occasion, some fights should be impossible, forcing the party to find some means other than violence to solve their problems.
As a DM, I usually have only one or two fights per sessions (and I'm known to have the occasional session with no combat at all). If I stuck to the CR of the party, they'd walk through the battles no problem. I think that,
on average, I use creatures (or combinations) anywhere from 2 to 4 levels above the party's level. That makes for a challenging fight and with
real danger, but the odds are still with the PCs.
As a player, I like the sense of danger, of knowing that my character could actually die. The only thing I want from the DM is that he made certain the fight wasn't
so high, in terms of EL or CR, that we have no chance of victory--and even if it is, if he's allowed us room to escape and come back from a different angle of approach later on, I'm okay with that, too.
AFAIAC, challenge rating, more than anything else in the book, is a very general guideline, not a hard and fast rule.
