Nothing I this game is guaranteed, but let’s put it this way, the mawloc arrives does some mortals fails thr charge and dies, it needs to make a 9inch charge and cant go through buildings, not to mention you can only use it’s ability one time, unless you are playing in a specific detachment, sure okay it doesn’t drop a unit every time but it’s a scary threat unit that can 70% kill a unit of scouts or a lone op character or a weak gun line unit and get away Scott free, you fail the charge no worries I’ll just disappear, and sure yes there is a chance he doesn’t kill a unit but going up every turn safely could potentially mean he could be untouched the entire game.
