ruthlessness is basically just free damage for your opponent when you're running a tightly knit swarm

just drop the ept and bump a Black to an Omega

Better yet, instead of an omega with crackshot, go mauler with crackshot.

I don't mix up the ages!

But, I like this:

I prefer 5 Black shot, 1 Obsidian and 1 Academy. I like to use 7 TIE in a swarm because I feel the extra ship is more beneficial for the extra attack, hull and blocking potential. I see Crack Shot as a replacement option for Howlrunner as the Black Shot swarm gives more flexibility in movement over a Howlrunner swarm. However, I've not yet flown the Black Shot swarm so I'm unsure whether it'll be replacing Howlrunner and 6 Obsidians. Both lists were flown at World's by great players but the Obsidian swarm did better.
