Playtested this unit against both the Japanese and Germans. It proved to be annoying to deal with (especially against the Japanese Air/Carrier/Cruiser build) the German Sub/Battleship build fared much better. The Screen was just enough to abort some planes, while the -1 attack die (not -1 to each attack die) from ship mains was annoying from cruisers... the German Battleship mains just didn't seem to care.
It is important to note that since there were 8 in the class this unit will be unlimited for the game.
For the build I usually paired The Quickmatch with the Arunta (6pts) and a Cruiser... That's 3 ships per sector for 13+Crusier cost. It's becomes a somewhat annoying yet competitive swarm build.
It did beat the Japanese, but lost to the Germans.
Honestly 8 points for what it does would still be worthwhile.
