i don't think dealing the majority of hull damage as a player is a given in any battle you'd win without problems, if the allied fleet is much larger. a lone player controlled Medusa with some combat skills can take on a rather sizeable pirate fleet, by whittling them down one by one. it's not that difficult or risky as long as you're patient (and don't overextend just to finish off a wounded Lasher.. <.<) but it can take a while (Hardened Subsystems hullmod is probably a good idea).
if the allied fleet has a bunch of destroyers and frigates, and maybe some fighters/bombers or cruisers as well, they would probably steamroll the pirates and do most of the hull damage in that fight.
It is like Sy wrote. With max Combat and Technology, I am good at demolishing non-bounty fleets with a couple Wolves or Medusa, and I do not want a meddling fleet stealing my kills. No, I cannot kill such pirate fleets immediately, it takes time to do so.
From a purely mechanical point of view, this situationally encourages a more aggressive playstyle, which I think is good. It's good to have an extra reason to mix up your tactics.
just not initiating such battles while allied fleets are in range obviously gets rid of this problem, just seems to me it would feel weird to have to do that.
Yeah, I hear you. On the one hand, it's maybe a bit gamey. On the other hand, being able to pick and choose what fleets you allow to join would be a pain for the player, also gamey (do you imagine an official patrol would really take "no, I got this" for an answer?), and much more complex to implement.
ai fleets just not joining battles that seem a sure victory should definitely help, although it depends on what they would consider as such a "sure victory". would they help said lone Medusa against a bunch of (D)-designated destroyers and frigates?^^ probably, considering a pirate fleet of that size also tends to initiate battles against the player that it won't win.
but then again, i guess the problem here is more with a single player controlled ship being so powerful (at least against very low-tech enemies) rather than with the expanded battles mechanics themselves.
They consider your (and your officer's) levels, but yeah, even so, it's very much going to err on the side of being safe.
Hmmm... perhaps if our transponders are off the allies won't know who we are, so won't "help" when we don't want them to? Or some other preference from that set?
Oh, right, forgot about that. Yes, if your transponder is off *and* they don't know who you are (i.e. didn't see you recently with the transponder on) then they won't join. And won't let you join an ongoing battle. But running with your transponder off in full view of patrols is generally not a good idea - you're only going to get away with it in independent space.
