Though there's still something I'm wondering about: After all these years of 3.0/3.5/PF, I dunno how many discussions about C/MD and as many tries to make fun of those people who don't buy the arguments, there's still noone out there trying to solve this assumed problem and having any form of relevant success with it. I'm guessing that's because of one sentence in this bingo stylesheet actually being true:
Fine, it exists, but it doesn't matter. At least not enough, that so many customers leave the system for that reason that Paizo would be forced to do something about it.
I hear 5e is doing pretty well with their greatly-diminished caster/martial disparity.
But, basically, I don't really care about it either. As long as people are having fun at my table, that's fine. I don't care if I DM for a party consisting entirely of martial characters, or if I played in one.
People can have fun despite the C/MD. We all admitted this a while ago.
