First Order Tie Pilot
Poggle the lesser
It is a mostly farmable team except tie pilot. He the most important part however. How the speed works is that Sidious poggle always go first on my team then I-88. He is now offense and speed buffed and lots of enemy team has negative debuffs. Usually his crit aoe will take will one person to half health or almost half health. Then tie fighter cleans up with auto attack hitting insane single target damage with advantage and offense buff he can one shot the lowest health enemy almost garunteed giving you a 4v5 off the bat.
What is great about this group is that all their basic attacks are amazing so even old Ben has no effect on them. You should be able to kill 1-2 enemies per round. I have not seen a team that can defend against it yet. You can't heal someone who dies in 1-2 attacks so healer teams are super easy as well.
Just don't expect to defend with this team since you can't focus fire as so you will get destroyed.
