When starting a new campaign there are some options to make these enemies easier to deal with. Use the Spark Mini-Gun mod to give Sparks stronger weapons that shred armor like crazy.
If using Covert Infiltration use the mod Strategy Overhaul Chain: Spark Heists to get Sparks at no cost except time. At campaign start use the option to double timers on missions. For Avenger defense prioritize getting the Defense Matrix as soon as possible. You need to autopsy turrets to do this,. Upgrade it once complete. When possible use a reaper, or similar class, to spot the device and take it out at range. On some maps this is easy, on others more difficult.

Part of me wonders if simply installing the mod that removes the cap on force limit, and increasing the units force level by 3 or five would fix it.
