Hi, i have been playing the dream from a quite a long time. Most of the time can see teams not in the contest or exactly the players who are performing in the game will drafted and team will be formed, also observed that if players are performing well they will be changed during the middle of the game.

I know it is possible to join the contest with 6 teams but concern is team winning in the grand leagues most of the team either team not existing in the contest after downloading and verifying the teams or players will be changed during the end of the game based the points players have got in the contest.

Feels like is it fake or will it be hacked by others or it is done by dream 11 team, mostly in grand leagues.

I request you to please provide the reason why this is happening, if this is genuine take care of all this things and help to play the fair game.
