Regarding push distance, my experience was seeing an enemy with some big pool of damaging surface behind them, pushing (via repelling eldrich blast I think, where it doesn't show you the arcs they'd fly in before you commit) and having them fly over the surface to land on it's other side.
The long pushes are over the top, they often leads to unpreventable player deaths.
I think part of the problem is the strong scaling push distance has with STR. A low STR can barely move the same target that a 18-20 STR will push over the chasm you cant see on the next room.
