I'm excited about Wave 3. I think Fleet Support upgrade is going to be huge. It's like adding Mini-Admirals to your fleet. Furthermore, with the flotillas being inexpensive units, you can add multiples to your fleet, making a tremendous number of different possible combinations.
Speaking of them being cheap, this now brings a whole new dimension to Activation advantages. Are people going to bring floods of flotillas to force the other player to deploy and move first? There could be a concern for slowing down the game, but with only one dice for attacks, these should be VERY fast activations.
And it increases the number of strategic choices in the game. Do you use one of your ship's attacks against a flotilla to try and reduce your opponent’s Fleet Supports? Do you use your attacks against larger targets worth more points and ignore the flotillas? What about maneuvering and trying to run over your opponent's flotillas? Or using your own flotillas in a suicide run to block other ships? (FFG, please have a self-destruct upgrade!)
Additionally, if you choose to attack flotillas, for the first time with a ship, you now have to deal with a Scatter defense. "Oh, you rolled enough damage to one-shot the flotilla? Scatter." Accuracies just gained some significant importance, and flotillas are going to just ignore black dice that don't have some kind of help.
Was I expecting more? Sure. We only have one large and medium ship per faction. But these two little additions are going to add a LOT of options for Fleet Building and Strategy. Giving us four additional ships that just fired X number of dice out of arcs wouldn't have affected the game anywhere NEAR as much as these two units.
I'm very happy with this announcement.
