How is this possible?

seems like they wait very close to the end to win. Pretty much no way the JKR team can beat JML. I'd lean towards cheating

The jkr win is highly sus, I just unlocked trayas omni so don't have much experience with it but to be able to clear jml and jmk seems like a huge reach

Also do you know if their savage has his omni?

Probably waiting out the clock to make it seem more legitimate because extremely short battles with oddball teams are usually a big red flag.

Given the protection banners on that Traya team, I think the guy is a cheater

Well this is my counter...In 1 minute he wiped my R8 Kylo out...Who do I contact to report this cheater?

I am not sure what you are saying.Let's suppose you are right,how do you explain the JKR counter?

Like others said, cheating my still be a factor. That being said, Yoda and his Grand Masters Training can do wonders.
The video link is of different compositions, but basically probably still the same tactics. The video, imo, shows a much harder GL team; and, the Attacker finishes with full health/protection.

The Kylo fight isn't cheating. Unlike JMK, SLKR isn't immune to TM manipulation plus you don't have Hux in your lineup. Dark Trooper goes first thanks to the 20% TM DC, he uses second special which makes his whole team go first then its game over. I regularly use Troopers with that DC against LV and sometimes JML & win

Honestly, the only one I'm not sure about is Traya vs. JmL, because I haven't encountered her omicron. That doesn't mean it's suspect, just that I don't know.

As for the rest, those are honestly really bad teams. Just having a GL doesn't make a team good. Who runs JMK with no CAT and throws in junk like Cody and Clone Sargeant? They even lost a character in that fight, which is usually a sign of not cheating.

For the Revan one, again, that's a pretty junk JML squad. With a fast modded Revan they could go first and start controlling things. Yes it's weird they don't seem to have damage, but there's also protection recovery on that team.

Like others have said, with no Hux, Troopers can easily beat a SLKR team with the likes of Phasma and FOX on it, especially with the tm datacron. Again, Gideon has damage to his health and not just protection, which is usually a sign of not cheating.
