If all you do is hunt then you can do it that way. There are people who shoot bows for something other than hunting. There are days when I may be shooting a couple inches one way or the other at 50 yards. Rather than fight the bow to get that couple inches I just adjust the sight. You have to accept the fact that to some of us that last little bit of accuracy is very important. And personally for me it's very rewarding to do so with my hunting bow, too.

Of course you don't go around adjusting things while hunting. All the little quirks should have been ironed out by then.
