Maybe he used a second account to buy a player off him for a very high price and lots of tokens?

It does seem that a lot of tokens have gone into the account, but its not known without doubt how the guy has got to that stage. Maybe he has bought a few packs, spent a few hundred, farmed a lot etc... to get to that point.

In some areas it is very easy to farm tokens. I used to be able to farm near 200 a day at one point (Could probably push 50/60 now a day if I had the time/desire even after they have made it harder) - who is to say that people in Vietnam also can't farm as easy as others - if not even easier.

The way you go around accusing people is not on. You may well be right but you need proof. You continually cry that people are cheating because they have very strong squads - the one you pick today is ridiculously strong - yet you lack the actual PROOF of wrong doing. It looks dodgy, but without knowing the other users methods you can not say he is cheating. You just come across as being bitter.
