So, I hit tier V in Romulan rep today and shelled out all the cash and dilithium to get the Ultra Rare Scorpion Hangar Pets for my HEC.
First impressions: Love.
I have used advanced peregrines for a long time, but these new scorps seem to really shell out the damage. They use their heavy plasma torpedoes a lot--during the Conduit tonight it looked like heavy plasma torps on parade with a line of the suckers heading in toward the gateway. I know some of them will get shot down, but with six fighters out all the time, that's a lot of torps for the bad guys to deal with.
Anyway, the cost is high, but so far it seems like quite an upgrade.
