I was lucky enough to get 2x decimators from GenCon and have been loving it. One advantage of having 2x decimators is having 4x ruthlessness upgrades. So, using those, here is my new idea for a TIE swam.
Howlrunner 18
Black Squadron Pilot with Ruthlessness x4 17x4
Black Squadron Pilot 14
Total 100pts
I know it's only 6 TIEs instead of 7, but the increase in damage potential and PS really seem worth it to me. Also, In our meta, there are three popular builds: 2x Falcon, Falcon + swarm, and Phantom+ lower agility ships. I think this list counters all of them fairly well. Finally, the glaring weakness to this list is, what do you do if your opponent parks one ship at range one of your swarm?
Any constructive criticisms are welcome.
