So how do you beat boba teams with good rng? Do you kill him first? I avoid him because he regenerates.
Depends what is Boba surrounded with. Usually he's 2nd/3rd unit to kill on the list. Why ? He has revive so you're almost never be able to kill him twice, especially considering that there will be a taunter/healer in team, not to mention your dps will be crippled cause of his ability block.
1st: main dps, preferably aoe - Lando, anakin, 86,88 droids
1st*: main crippler or obstancle in your tactic: QGJ (if you run sth you have to take him out because of his despell or dont use sth then), palpatine, vader, sth (if wiggs took out your only dispeller off the bat or dispeller got ability blocked after he moved)
2nd: secondary aoe dps (if there was any), supporters or buffers that can ressurrect (daka, jyn) or benefit from deaths (assaji)
3rd: Boba all the way
This list is not conclusive since it depends what you're running. Against Boba you have to have good burst dmg ready, so assisted attacks fare well here. Sometimes I wait with killing him even further if there is a high chance one of my units will die shortly. It's better to sacrafice him and attack someone elsse, than deal with second Boba ress.
Sometimes you're royally duped and Boba cock blocks all 5 of your units and then you pray...
- Chaze: What do you do against Baze? I focus now strongly on Sun Fac. I hope clearing the Buffs will do the trick.
My best tactic for him currently is based solely on Lando. With QGJ I dispell him first round, attack my worst opponents, preferably Lando (most cases). Wait and pray Lando can score crits both turns and I dont get unnecesary death. After that Chirrut is below 100% health and baze taunt kicks in. Dispell it with Boba (if you run him) or with QGJ next round, he will have it off CD. In this scenario decimate Chirrut once his second taunt is off. Worked for me twice already, but it's because it's the only way for me to win. Still figuring out how to go agaisnt chaze/wiggs, but probably it's impossible.
