At its best, crushing hand is trip with a saving throw. You will always get a command between hands if you don't waste it.

I could see crushing hand being treated like pebble to boulder by the new anti-ganging code if it isn't already. In a non-extreme-ganging situation, any character that is set up (which includes, but is not nearly limited to even at the gearing level, saving throw equipment) to die to this tactic is also going to die to about a thousand much easier to execute tactics.
