I think it's a bit premature to get worked up about the few hunter changes we know about, since we don't know what else is going on. We still don't have talent trees, we still don't know what other mechanics changes are going on with our class. I'd feel pretty stupid if I posted big rants like this and then it turned out that blizzard was doing something like, say, significantly increasing our mana regeneration so we can dps for 10% longer before we run out of mana? That'd cover your math problem pretty well, I think. Once all the changes are known, by all means, raise the red flag if they're bad. Until then, it's just a chicken little sort of thing.
