Read the blue post from the game producer. It is in the OP of the thread linked below. Their projected max GR target is 141 in non-season. Crusaders are @ 150 in non-season.
My point is simply this: Everyone should feel free to express their opinions (even if they contradict Blizzards) as long as the poster follow Blizzard’s forum rules. You have every right to say that you disagree as long as it is done correctly. Others who favor the offline option should be allowed to express their view.
