Cheater nr1 on leaderboard?
If you check the Strongest Team leaderboard there seems to possibly be a cheater that has had the number onespot for over a week now.
Over 300k in comparison to the 200k for spot number two.
Might be bugged, cant say for sure its a cheater but it seems likely. I dont think its possible whatsoever even with synergy to get a team to that kind of rating at the moment.
