It's more deeply ingrained than that. There's the healing surges*, and the fruity powers that leave flavour as an afterthought, the dragonborn staring up at me from the artwork, random stuff like jailers being evil, the arbitrary alignments left over from the older game, the existence of warlords which actively piss me off at how much hubris and no right to exist they have...the whole package is too incohesive, such that I don't want to work for this game. The illusion isn't good enough.
*Why couldn't they have just called a second wind something like "luck"? Run out of luck and you die. Spend some luck to get hit points back. "Healing surge" suggests exactly what you shouldn't be thinking about when trying to envision how the hit point pool works, that wounds magically seal over due to a burst of energy. I can buy that the PCs are somehow Heroes of Destiny and therefore have more luck than their opponents, something like that would float, but what they've come up with seems half-baked.
