A new factions means new bad lists to try out!

I like the variety.

Muk list: Though it may be fun and certainly has some damage potential with this vets, this build has low hit points and Leechos just doesn't seem to add much. I'd trade him out for a 24pt y-wing.

Viper strike: I'm also a fan of the vipers. Played my first game with scum today and flew a generic viper. They are decently maneuverable (the s loop is grwat), but firing without modifiers is certainly not ideal. Vipers are like PtL interceptors. Wish they had an elite generic or even more interesting would be systems slot on all vipers. Regarding your list, I'd probably drop one enforcer & upgrades for some z95s (3 preferably).

Dancing Kath: like it except wingman. Just don't think it's worth the premium.

Ion: looks like a headache for the opponent

Xisor: Fun. Might try 5 zp5s with him also.

You didn't give Scyk heavy to one of the M3s in Dancing Kath. Couldn't afford that last wingman. I'm not big on wingman either.

I go 20pts per M3 using cheapest pilot, heavy, and mangler. Maybe splurge on an stealth device if I can afford it.
