Yeah I need to make a comment here. Twice I've been wrecked by heatseeking missiles, both times by being interdicted by two Mk III cobras.
Cobras have a huge amount of hull, they're fast as hell, and there were TWO of them. My only choice was to outrun them, but even going 320 permanently wasn't enough to get away from them OR the missiles. And now, looking up the subject, it seems like there are almost NO countermeasures to missiles? What?!
The chaff doesn't effect them, and the heatsink takes way too long. Missiles track aggressively, do tons of damage (even on shields), and can go pretty far. Without taking up one of my valuable hardpoints with a point defense, I'm totally vulnerable. That means if I'm up against ANYONE with a missile launcher, I'm screwed, and there's nothing I can do about it. This needs to be changed.
My only options are to use a PD (meaning I'd only have one weapon), fire a heatsink (pray it deploys in time and distracts all the missiles and not just one), or run away (which, to do successfully and reliably, would mean running before you know what ships are there and whether they're wanted, depriving you of potential bounty gains).
Am I missing something? Those are all pretty crappy options and it makes me irritated as hell. I don't like the idea of something being able to wreck me under 95% of the circumstances.
