I'm one of those rare people who love fleets. The main issue now is that the meta is dominated by HT+Falcon, which CG seems eager to address. I don't want those ships to become useless but I do want to have some variety so that a smart player can win with different fleets (especially important for new players, so they can pursue different avenues to success).
One thing I would like: more thing to do with my fleets! The new post mentions a potential raid. But how about a ship assault battle? That would really leverage the unique aspects of ships (reinforcement abilities, in particular). Something like Destroy the Executor. Use your ships to fight through waves of tie fighters, take out the shield generators, then destroy the bridge. Rework your fleet reinforcement so that ship-to-ship dominators like the Falcon come first then bombers finish the job in the later stages. Or recreate Poe's attack on dreadnaught. You could even introduce real bombers (B-Wing, Y-wing, MG-100) that aren't good against other fighters but can affect the enemy capital ship or be used only in a raid/assault battle context.
There are so many possibilities of what to do with ships outside of arena. I want more ships; but what I really want is more to do with them.
