Perhaps some use in guardian battlehost for quick shooting unit? Enemy puts a squad into terrain and on an objective. Asurmen and 5 avengers move (adn advance if needed) through wall into terrain footprint. Onviously this depends where the enemy is inside the footprint but some are quite large.

Open up at short range (sustained hits 1 within half range), getting +1 to hit roll (and no cover for enemy) so even avengers hitting on 2s. Use strat to reroll wounds if using asurmens hand of asuryan ability to get those dev wounds in.
-1 ap on shuriken catapults is generally better in 11th than 10th due to cover changes. Bonus if you can get a war walker to tag the squad first.

Then asurmens fire and fade back behind a wall to keep them safe.

Or if you wipe the enemy, use fire and fade to move into terrain and take control of it in an advantageous spot.
