I generally don't take Shield Drones on anything other than Stealth Suits or Commanders, and have had very successful games when I deploy maximum Gun Drones with my Manta Striking Crisis Suits. The amount of firepower you can put downwind is just too good to pass up. Sure, they're not as resilient as Shield Drones when you use them as ablative wounds, but when you absolutely need a unit deleted this turn they're very good at doing just that.Arka0415 wrote:The reason I wouldn't use a hard-and-fast rule is that Drones perform different functions on different Battlesuits. For example, a Commander with Missile Pods shouldn't take any drones. A regular XV8 squad should take 6 Drones because that's viable for Manta Strike, and a Fusion Commander should take Shield Drones to make use of the Character rule.
I tend to max out on Crisis Suits when I deploy them, so having 12 drones mean 48 shots. I take on the mentality of a Guard player: One of them will hit and wound eventually! I usually take 2x Plasma or CiB and either a Flamer or Missile Pod depending on what I'm expecting to have trouble with. It's worked very well for me against Ultramarines. 6d6 S4 attacks is no joke, even if they don't crack armor as well as the plasma.
