I think that specific parts of the game created by one designer can certainly go against a philosphy espoused by other designers or the designers as a group. At any rate, I think all of the mundane items that give minor bonuses to skills are completely unnecessary and (while they in no way break the game) they are flaws which I wish weren't there (mostly for aesthetic reasons).
To me, it is fairly clear that 4e's designers don't embrace the idea that simulationist tendencies are taboo.
While 4e certainly takes big steps away from simulating, no game that has a friggin'
encumbrance system is going to ever achieve that escape velocity.
D&D in general has a grand tradition of accounting that I've ignored, by and large, but I don't think the game would necessarily be any better in any absolute sense for abandoning it. Maybe closer to what I play, but I'm not going to assume that what I play is what should be played by all people who play D&D.
I'm really OK with the game providing a boost for people who want and enjoy that kind of thing. Rather than making the game worse, I think it makes the game more diverse and inclusive, and it doesn't hurt me one bit. I'm certainly not intimidated by a bevy of +1 bonuses (easily limited by being the same type anyway) to a check that, at best, grants you a success in a skill challenge that the rest of your party might still fail for you. I am confident enough in my DM authority that whenever someone says "Nuh-uh!" I can say, "Are you five?"
I don't get the hatred of these fiddly bits. I get not really using them -- I don't really use them -- but I don't get how their presence is somehow a philosophical anathema upon to the edition, or the paranoia that it will unleash a catastrophic avalanche of +1's.
Some people want donkeyhorse braybeasts. I'm really OK with the game giving them donkeyhorse braybeasts. Just like I'm OK with the game giving Conan dorks a ready-made evil wizard race, even if I'm not a fan of the new Tiefling, and I think Conan is a juvenile power fantasy. I'm OK with sharing this game with people who play it differently than me.
