I've achieved top 30 in every single game mode since the release of the game, except toi so yes i play high rating and thats why i can say the classes werent anymore balanced, at least regarding 6v6 , my ms is 170+ so i cant fully say whats balanced 1v1 wise as the top 5 is crowded by people with 100 ms or less rather than actually skilled players
but yes in 6v6 ranged classes always had an unfair advantage since they were as tanky as melee and did much more damage with no risk compared to melee
