Yeah. And it sucks, because people kinda have a stake in the specific kinds of resource schedules D&D uses--to the point that they may assert that lacking those specific schedules is enough to harm or even ruin the game!--which makes it doubly hard to have any kind of conversation about making things better.
Yeah....it's tough. For some, to even broach the question of "do we need different resource schedules" is tantamount to completely erasing all differences between all characters. And when you have that strident a view on it, discussion is pretty much impossible; to deviate is to destroy, thus there can be no thought of how things might do better if done differently. Naturally, we all have subjective lines that we struggle to accept any change past, but this particular one is so endemic to D&D-based games (including, as Campbell noted, SR and some other not-actually-D&D games), and so deeply polarized, it's...kind of without compare. Either you totally buy that stark differences in resource schedules are completely compatible with "sufficient" balance (whatever definition we give "sufficient"), or you don't absolutely buy that, and ne'er the twain shall meet.
