Unless something changed in the recent patch, that is not my experience. Shove archs seems to autoadjust and extend to accomodate characters being shoved down, and archs can get very generous if there is even a slight decrese in elevation. In combat encounters in forge and in goblin's hideout not getting pushed down has been dominating those encounter everytime I did them and limited combat options to few limited spots on the map.
