It'd be hard to define STRIKE other than arbitrarily, though. For example, is a Medusa armed with a pair of Heavy Maulers and a bunch of Vulcans STRIKE or is it a kiting ship that can absorb a lot of missiles? It can do both. Do we want a Destroyer to attempt to face-hug an Onslaught, or keep well away on general principles?
Doing it by System might be most-helpful, but there are issues there as well.
An Onslaught with Burn Drive recharging is a sitting duck and a tail-chase might be very helpful, if the ship can do that, but a Medusa is just a few seconds away from being able to warp behind you and a Hyperion is probably about to do something very nasty to your engines and then it will avoid being face-hugged in turn quite easily.
It's probably easier to simply balance those Systems a bit better, tbh; if they're a little too useful for alpha-strike behaviors, to the point where ships are worth far more than anything else in their class, they probably need a nerf.
Medusas would lose quite a bit of alpha-strike if Skimmer took a couple more seconds to charge; Onslaughts, imo at least, aren't terribly OP, Hyperions largely just needed their teleporter's recharge increased quite a bit, so that they could get in... but not get out so easily. Then again, I remember when they were like evil pogo sticks and could get another teleport going about when their shots landed, lol; it's a little better now, but that's probably the best way to balance ships that are almost entirely about that concept.
That said, almost all of the alpha-strike "abuse" is player-driven, and has more to do with the AI not quite mobbing the player as well as it might.
