The new card system they put on pts is bs and force to grind to much to play in casual at an even level with other players and even then the game is not balanced, because it allow to have all cards level 5 and that is op af. So the new card system force people to play ranked for a more or less balanced game, which means that players that just want to play casualy or try weird loadouts just to have fun wont be able to do it ranked.
