With nobody else having replied to this, I'm gonna load it up and give it a try. Unless procrastination prevents it, I'll post my impression after completing it.
Edit: I'm gonna focus on what I didn't like since you'll probably appreciate some constructive criticism, okay?
Way too many enemy craft, way too many friendly, which presented some problems which I'll elaborate on later. While it was chaotic, it didn't feel tense. It was like I kind of slumped back and forth taking out beams while a lot of not-really-important stuff was going on behind me, but this might have been due to the fact that the music stopped playing for some reason on what I think was me second try. I lost a friendly ship in the back to enemies, because there was no way I could do both -- I couldn't de-beak the cruisers, save the cruiser in the back, and ward off fighters at the same time. On the same topic, later in the mission, I found out, to my horror, that for some reason, the Franklin cruiser was way, way ahead of the Hebe for some reason. In the mind-numbing grand scheme of things, I just hadn't really noticed it. I managed to save it, though. In the end, having taken out all the warships, the shivan bombers that appeared from over 10,000 meters away seemed like they were just delaying the end.
Anyway, the way I played the mission was to just load up on maxim guns and trebuchets, which didn't really seem to work. The amount of enemies and action also seemed to make the controls unresponsive at time, which was problematic because I was relying on my Maxim guns to take out threats to the Hebe.
Also, the Thanatos absolutely blindsided me on my first go-around - It didn't appear on the target list. I wasn't warned about it, and I had been operating on the Hecate's port side the whole time. It might have been mentioned in the messages, but I didn't really pay attention to them -- Too focused on the de-beaming task and the occasional fighter that crept up on me.
Now, suggestions: Cut out the freighters, cargo ships, and about half of all fighters and sentry guns present in the mission. Basically, rethinking the scale of the mission is the thing that jumps to mind as the biggest thing that could benefit this mission. It would bring better performance, more focused action, etc.
