Just throwing this one out there as an alternative way to use squadrons.
The two main ways I've seen so far that squadrons are used is either:
- Uncontrolled: often completely left to operate on their own. Has the advantage of not tying squadrons to ships, but loses a lot of synergies and attacking opportunities as you really need to have them in the right place at the right time.
- Controlled: where they are directly controlled by a carrier through squadron orders. This can be very effective in enhancing a given ship's damage potential, but can be limited by the number of squadrons you can activate. Also runs the risk of the carrier being taken out and your fleet suffering disproportionately as a result.
So, would it work if you were to launch a "cloud" of squadrons that are intended to cover a broader area, and then control them as/when needed by ships to augment their own attacks?
For example, you could have up to 10 x-wing squadrons in 400 points. These could cover a large area, but it's unlikely that you'll have the squadron activations for all of them at the same time. But this isn't critical as you only activate the squadrons that are in the right position at that time and that are advantageous to that ship. The rest remain as a "pool" to be either used by other ships, or to be re-positioned/attack in the squadron phase. Boosted Comms and Wing Commanders will increase your flexibility in using your squadron could.
This tactic works quite well for imperials with Rhymer too: you launch a cloud of TIEs/Bombers and then only move Rhymer to the part of the cloud that you need at a given time. Since the rest of the could has been static, they get the shooting benefit in the squadron phase.
The deployment of this would also depend on what your opponent is fielding. If they are also squadron heavy, then you can concentrate your forces and engage in a dog fight, of they are ship heavy then you can spread out so he can't avoid them.
