I confess, it seems to be getting further and further form 2.5, and that alone is a big Red Flag for me.
Simplicity is a tricky thing to manage - especially when we live in a world where thinking seems to be an anathema - and while a certain amount of simplification is desirable, games often end up as complex variants of "Paper Scissors Rock"/Roshambo rather than an actual war game. 3.0 was already simplified from previous incarnations, and that was half the problem ( All ships of all sizes use the same turn template? Really?) for many players in my group.
Still, trying to be optimistic, I suppose the doing away with weapons arcs might help some people with the game nevertheless that's really an important feature of naval and other fleet combat games, and I don't see how exactly it will work and still retain the feel of naval combat in all honesty. But if they make it work, then great.
