For me, Neferhet, it still is an interesting discussion! Mostly due to my inability and/or impediment to manage to post here often...

.
I like the Cobras because of the array you can get by replacing the weapons battery (it was useful against the Official Necrons... and their phased travel...), and I call mine Eyeglass Squadron. The name helps justify them

I really do think there is a problem with escorts. Currently there are three main types of escort: torpedo boats, lance boats and gunboats. Combinations of those occur too but they generally get used as one of those in my games. From the fleets and discussions that I have seen, the most popular ones are the gunboats, followed by the torpedo boats; lance boats lose out. And gunboats are there generally because you can get some good firepower from Sword squadrons (etc.). Changing the weapons batteries around gives the lance and torpedo boats a stronger role, that of 'destroyer' ships, whilst weapons battery ships are more for escort/general duties. With this clearer division, and cheaper lance boats, lance-armed escorts could be real choices for cheap and dangerous anti-capital firepower.
To me, this seems to be the design problem: if you go through all the effort to make a fundamental distinction between two different types of vessels (escorts and capital ships), they should have fundamentally different roles in the game or else why include the differences? BFG is really good at doing cruiser-sized ship interactions (in my opinion anyway

) and I think that real firepower should come from the bigger ships (after all, they are big for a reason...) while escorts do more escort-y things.
But at least escorts still do the job of protecting the back of the big, slow Imperials

. Only problem with hitting ordnance on a 4+ is that the lance boats and gunboats are about as effective as each other, so why pay the premium for lances?
Maybe we'll hit upon a golden solution for escorts: whilst making BFG even better is good, we mustn't forget that BFG is pretty cool already

Food for thought,
