It sounds like what he's really saying is that high strength characters are game breakingly overpowered and need to be nerfed IMMEDIATELY! Maybe cap Strength at 14 or 15 during character creation.

None of my non-strength based characters have been able to throw people around and usually can't even get a successful "Shove" going. It's just a wasted turn so I don't use Shove. I'll throw grease bottles though.

They could nerf Lae'Zel, too, then. Maybe drop her strength to 15 and bump her Con or Dex. (should probably put it into Charisma to be honest. She could use a boost there)
