Meanwhile the Vultures still swarm really well (and a lot of Hyenas got cheaper). No Belbullab means no Sear, but Sear is nowhere near as core to droid swarms as Howlrunner is to TIE swarms. The Sith Infiltrator can still carry a tactical relay (and TA-175 got a price increase but also got a nice timing buff in the rules update*). The droids lost Energy Shell Charges but results have already proved that droids are just as good without them.
*TA-175 now activates after the kill-shot is resolved, not after the ship is removed from play. That makes a big difference in many cases of simultaneous fire.
