From 5 stars to 3 to 1 the ranked system is garbage, 1 team always completly overwhelms the other, the matchmaking system makes all the matches somehow rather too easy or too hard there is nothing fun in that. you could get put with trainers with any ranks 2: some pokemon are overpowered, especially if a speedster like absol and zeraora farms well and is a level or two above other pokemon, it can literally KO 3 pokemon in seconds and escape in any situation due to having dash skills, nerf them!!
