The concensus seems to be pretty clear that a pair of them is pretty much necessary on BASS teams, and with that I agree, but I seem to be getting conflicting messages on their use in other units. Their usefulness isn't something that can be easily calculated, since one must take into account numerous factors, such as the unit's ability to avoid incoming fire through use of terrain or stealth, the overall necessity of keeping the unit alive, and the cost/effectiveness of simply using the points to buy more guns. I've seen some people who give them to all their squads, others who don't use any at all, and still others that give them to some squads, but not others.
Since I didn't see a thread dedicated to the subject as I skimmed back through the archives, I was just hoping to hear to what extent people use shield drones, on what units, and their reasonings behind doing so. Hopefully, that will spur some discussion, and we may be able to come up with a few guidelines for the newer people. Either that, or the opposing camps will just dig in and mock each other mercilessly
Personally, I see shield drones attached to Fire Warriors or Pathfinders as a complete and utter waste. They simply aren't worth enough points to make them worthwhile. Also, I never use them on Stealth units, since the stealth field provides ample protection from shooting. It's with Crisis teams, though, that I'm torn. Currently, I give them to any squads armed with shorter range weapons (Aurora, Helios), while leaving them off the longer range variants (Deathrain). Fireknife, though, is sort of in the middle of the pack, so it poses a conundrum. Additionally, I'm undecided as to whether or not any HQ units with bodyguards should automatically get first priority, regardless of their loadouts, in order to protect their higher points costs.
That's my two cents, anyway. Thoughts?
