Solid points about illicit slot adding diversity on the Z's. I guess I just wish they had a 3-primary low-20's efficient filler like a B.Off topic-ish, but I'd be delighted to have another HWK title, exclusive to Scum.
As for filler, I feel Y's and Z's fill the roles nicely, given the plethora of options; feedback, turret, hot shot, etc. Kihraxz and loaded M3s may be more spendy in general, but not outside the area of a Y-Thug. TLT Thugs are awesome, but it really depends on the rest of your list and how they complement one another.
You mean like the Kihraxz?
23 point 5 PS Black Sun Ace can take an elite pilot talent, and an illicit upgrade. There's a lot you can do with that.
There are worst picks than 1 or 2 Cartel Marauders as filler.
