If you want monster just jumping on you all the time, go play Mario brothers. That's what those fights devolve into. It's neither interesting nore balanced by the rule at all. I have DMed DnD since 1st ed ADnD, and no, blatently making up your own combat rules for an established creature as a normal thing is bad DMing, not adding flavor.
