I like it, good points!
One thing I thought of...A partial point system for the large base turret ships means those ships will virtually never win 100-0. I know this is what we are looking for, so players get credit for the damage done, but it seems funny. Consider those situations when playing against something like 4 B Wings, 2 of them sitting at 1 hp when they finish off the last ship, giving a 100-0 score to the B Wings. Turrets will be automatically incapable of this when they lose shields + 1 hull, which stinks, even when they kill an entire 100 pt squad within the time limits. Maybe that's enough to curb the MoV advantage for the big ships with Engine upgrades, but the big ships that are relying on that hull to out-trade (essentially joust) and don't take engine are worse off than they already were, even if the squad would traditionally score a 100-0 win.
The problem I'm having is, if we run away our 1 HP small ship (could be a 46 pt Defender), we are praised for "good play" or our opponent is berated for "lack of focus fire". But if our turret ship escapes with 1 hp, we are calling this "fundamentally incorrect and needs to be fixed".
Hmm, I think that's all a moot point, now that I think about it. We are trying to curb the obvious MoV advantage these ships have, which is obviously present.
The law of unintended consequences strikes again! You are absolutely correct that with a partial MOV change, any ship that surrenders some of it's points with partial damage will be incapable of winning 100-0. That's a bad outcome.
FFG probably just needs to stop releasing defensive upgrades. A little over a year ago creating a defensive ship was foolish. The defensive upgrades didn't do enough to make them worthwhile, I'm looking at you Elusiveness and Flight Instructor. But now, some of the defenses are so good and so powerful you just have to take them.
FFG appears to be making it a point to punish players that are flying unnamed pilots and swarms. Look at Predator, Whisper, Autothrusters has suddenly made the Interceptor playable. A year or so ago playing named pilots was viewed as a waste of points in a lot of circles, but now you can get tons of value out of high PS named pilots. I just think what we are seeing in the game today is a result of FFG's pro named pilot strategy as of late. This game would be so boring if it was 8 tie swarm vs 8 tie swarm over and over again trying to evaluate how each and every collision would end for 16 ships in a giant furball. It's better that the game is much more opened up now.
I still don't think this is a problem that needs a solution.
