The burning decks would be nice eye candy, but not much different from a burning hangar. After a couple minutes, you stop paying attention to it. The idea of progressive damage does have its appeal though. If it currently takes 8k worth of bombs to sink the CV, then shouldn't the fuel or the ack or at least the ordinance be disabled after 4-5k worth of bombs have hit it? I don't need to see holes in the sides of the ship and the deck listing at a weird angle, I'd just like to see the hogs and zeros only able to up with 25% gas and no bombs.
Leads to an interesting point about troops. You have to get the CV pretty close for the LVTs to spawn near the shoreline, but at the same time you don't want to get too close because if the troops get disabled, it's all in vain....wow, people might actually have to protect the fleets! What a concept!
