Of all of these I think I be most comfortable taking the 4 Tempest w/ Cluster Missles and AC against a fat turret or dual fat turret build (or maybe just about any build). Hmmmmmmm.......

Sum of all Fears:

x4 Sigma's

16 Attack Dice and 20 at range 1. This is a strong alpha and it has sustained attack values as well. The 4 attack dice will hit targets that lots of 2 dice attacks will miss. Of course you only have 16 total health so you die pretty quick.

4 Sigmas are a Wolf Pack.

Surround the enemy and attack from all directions.

You could to some decent damage and then cloak and run with damaged Phantoms.

Thats exactly what stealth fighters would do.

And if the opponent tries to hunt them down, the undamaged Phantoms have good chances to hunt the hunters.

Of course you can go unlucky with your moves and dice pretty quickly. Its risky but fun.
