I really don't get the "weak aces" comment. Just because someone doesn't have PTL doesn't mean it's a bad ship. I do think Xizor needs to take VI, but so what? Load up with FCS and Autothrusters and he's good. What's "weak" about him?
It's 37pt minimum with that setup, with no initiative bid and no body guards. I think it's fine, but it's hard to argue for that Xizor at 37pts compared to what 35pts worth of Vader or Soontir can get you, imho.
The 2 more points of pocket change get you a far tougher Vader (not sure how ATC stacks v 3 dice + FCS, though) And a far harder hitting, more forgiving and less **** giving soontir
Xizor can hang with (and ruthlessly murder) the big Boys
Any deficiency is exaggerated or purely imaginary; xizor kicks ass
His z-95s...not so much. Hoping the mist hunter brings more competent minions
