I found a cheater yesterday.

Both of these look like legit battles. Bo Katan is one of the best counters to Lv and a fully upgraded wampa with a maxed out fdc can beat most squads.

Yeah both of those are standard counters. The wampa against Jabba with 50rt cron is dicey though. But any other Jabba config is just fine.

You would be wrong. You need to look up counters before assuming someone is cheating 

sry I know the counters,maybe you can pay attention to the health and protection.

And my Jabba has a 150% potency datacron，don't forget it bro，i don't think Wampa can keep full of health and protection win Jabba with this datacron. i think you can try it in TW tomorrow. BTW,this Wampa's mod is bad...

Wampa vs Jabba: Jabba has 150% potency FDC, Wampa is low relics, but Jabba's team also has low relics. It's possible that Wampa could have survived the initial onslaught and if she does, Wampacron gives her so much offense that she probably wiped out Boushh with one AOE. I don't see any outright evidence of cheating there. 

BKM vs LV: Mandos have lower relics, LV team is full R9, Scorch has the omicron, no ROLO FDC for BKM and the battle took 78 seconds... If the battle clock said 4min18s I would say it's probably legit. BKM vs LV Clones is tougher than classic LV, but not impossible. However, mowing down an R9 team in less than 90 seconds? That's definitely sus. What's the datacron on the BKM squad?

BKM vs LV Clones doesn't happen in 78 seconds. 

BKM winning against a full R9 LV Clones in 78 seconds? Battle length makes it at least sus imo. 

That’s all the battles under 80 seconds in Kyber vs that team with Vader cronso yea, it’s easily possible. With ROLO cron they can go down fast in my experience

The BKM team in OP's screenshot doesn't have the ROLO FDC. 

There's no battle time timer in your screenshot.
