One of these two would be my "one thing"
1. A more complex damage model for ships. Compartmentalize the model to allow it to take on water when hit below the water line, allow for fire to ravage a ship. I'd like a bit more variaty in ship sinking "holy ****, that things still floating!" to "OMFG that ship just blew the **** up!"
or 2. Armor piercing bomds for anti-shipping strikes. Making people choose what to hit before they launch might not be a really big deal in the MA, but it would add a nice touch to events IMHO.
I'm thinking about putting together a care package for HTC, consisting of
1. A copy of Clash of Titans
2. The Game "Fighting Steele"
3. A bottle of scotch.
Might need two bottles lol.
