Trygons are an assault unit with Fleet; they can't assault the turn they DS. I would say ST are a much better candidate for DSing than a Trygon.
Flavius really nailed this question with his answers, though.
The failure of trygons tends to be the making or breaking of 'nids for this reason. Have you tried killing a tygon? Or indeed tried to open any mech with tyranids?
DoA means you can nearly always try to land within melta distance, it is not likely that you scatter that far. Even with the reroll the stormtroopers scatter far when they miss, which they can. Maybe 54% would be good enough if they can earlier.
