It seems common because only those peoples who like this game a lot are a member of the forum and are posting regularly...So they all are buying tokens, farming tokens or putting a lot of effort and time in the game...
Hence their teams are too strong for others...I have been playing this game for 9 months and have never seen a 26-0-0...Only in the forum I have seen many teams with 26-0-0 and trebles......
