Question, I understand how strong boba fett is in arena compared to QGJ, but before sun fac and boba fett how did you manage with taunts without a dispel?
You're missing the point here. This team is a high speed/dps team, who takes first turn. As such - in many cases taunters wont have the chance to taunt, at least until you take out main dps. JC is a back up for when someone is faster than you or you get bad RNG. I would always choose to do dmg first and block taunt, than be second and have to use dispel to get taunt out. Overall Boba's Execute skill dispels taunts as well, he himself bypasses them.
In some ways I like how strong QGJ is in the early stages and how it brought me to rank 2 today, and I do want to get boba fett, but wondering if I should leave QGJ when i get 4* or go 7*.
Smth being good doesn't mean that smth else can't be better.
Also, I've been trying to figure out how to beat Lando/Rey without access to counters like shoretrooper/barris zeta etc., I see people talking about in older arena shards, I've had a success today bursting down lando to get rank 2.
W/o knowing full party composition on both sides discussion is futile. First thing that comes into mind - ability block with Boba and burst.
