in platinum 3 is impossible rank up to the next division because the system no stop match me with oranges highers ranks or 5+ stars, or with Red heroes when for a player with low might cant defeat a red team or 5+ stars teams, sometimes I think that some players in the leagues agree to take turns between positions 1 to 10 so as not to let other players pass and change their names after a merge or before for confuse other participants,
in coliseum im in challenger league with red players too, but happens the same problem as in arena, the highers players take turns for no allow to the others players get a rank in gold and platinum leagues,
