Way back before the first big FAQs came out revamping shield drones (and before I realized that Sense of Stone didn't effect drones) I had a small point CQC list featuring flamersuits + a Drone Contoller, a mob of shield drones, an ethereal, and a couple strike teams for support.
The idea was to get up in the enemy's face right at the beginning, flamers and rifles blazing, then charge the shield drones right into their lines. The DC allowed the drones to hit even in melee on 4+ (it does say add 1 to any hit rolls). Next turn, fall back behind Crisis suits in such a way that after shooting phase can use saviour protocols while crisis suits charge into melee. Next turn, suits fall back and drones charge again, repeating the cycle and not allowing the enemy's troops to ever really get to fire during shooting phase, all the while using Sense of Stone to boost the drones' and suits' defenses.
This was, again, a low points game, and also utilized a rule I hadn't quite gotten right, but it sure was frustrating to play against the layered retreating CQC line strategy.
