It's a tactic so good you should always do it.
It's a fighter save or suck spell.
I think that you missed Patrick's point:
Actually pulling that off is going to be difficult. If you need three tries before you're successful, then that's three attacks worth of damage you just gave up to perform it. More if you're actually using the disarm-shove combination to stop him picking it back up.
