What's this about combat efficiency? Do units that survive combat get greater skills? Haven't noticed that so far. Think I've noticed Hellcats arriving on scene though, brutal to the Japs.
I wish a few things that are transparent would be more visible, such as I'd like Wildcat graphics early on, then Hellcat graphics later. Devastors early on then Avengers, etc. Wouldn't be too hard I'd imagine. You could still just label them "fighters" and "torpedo bombers" just change the graphic.
