I was just about to say I agreed when I decided to check the updated manual and had a nice surprise:
"
Tip: While combat is resolved one-on-one, if the defender is in a fleet, they do get some bonuses,
reflecting the support the other ships can provide.
Tip: If a fleet is attacked, the vessel with the highest combined attack and defense values will defend
first. If there are two ships with the same value, then the ship with the highest remaining hit points
defends. On the plus side, this means that the damaged ships will be sheltered by other ships of the
same class. On the down side, you can’t get a BattleAxe commander to throw his ship away
defending a damaged Dreadnaught: the BattleAxe will hide behind the Dreadnaught until the
Dreadnaught is destroyed, and only then fight.
Tip: When attacking, you can choose which ships attacks first, allowing you to throw away cheaper
vessels to ‘soften up’ your target, but only by selecting the attacking ships individually – if you
attack with a fleet, the ‘strongest’ ship attacks. NOTE: In attacking, every vessel in the fleet uses up
a movement point for each attack, even if it is not actually attacking itself."
Good news!
