How to use in your fleet
Gravity Drainers should not be underestimated - they are mobile Gravitational Turrets with a strong attack and large area of effect. As most ships in AI War are not immune to gravity effects, adding these to your fleet will make kiting a simple affair in every engagement. Therefore, these combine well with Missile Frigates and other long-range ships. Note that Gravity Drainers hard counter all melee ships.
Pre-emptively spacing a few Grav Drains around hostile wormholes will provide you with a handy counter to fast marauding ships. NB: Raptors and Hunter/Killers are immune to gravity effects, as are exo-waves until the lead ship has been destroyed (make that a priority!).
How to counter when in the AI fleet
An AI unlock will unavoidably cause some frustrations and heavy losses due to the Drainer's escorts, since most ships engage at 7000 range or below. Their composite hulls can be countered by the player's Missile Frigates; alternatively, they can be selectively targeted by bonus ship-types that engage at range (Zenith Bombards, Snipers, Sentinel Frigates, etc.) If one is lacking in the ranged-combat department a few slow and ponderous Plasma Siege Starships will help: it's not like you're going anywhere in a hurry.
Note that all Spire ships are immune to Reclamation and paralysis.
