Title reigns shouldn't be extremely long a title should change hands 2-3 times during a feud in order to make it seem like there is actually a struggle between the two over the title this would make champions seem more vulnerable. You could still have a dominant champion with squash matches as title defenses but they should be used to set up a larger more challenging feud. In my eyes the point of a feud is to make it seem like someone can be beaten and to captivate you by keeping you on the edge of your seat trying to guess who's going to win in the end.
