I believe that the game is still growing and that this problem is going to persist if not get worse. If this is really the case, then I do not believe they can justify charging a subscription, especially to players whose only playtime is during peak queue hours. They need to pause charging for subscriptions until the queues die down or until they are able to increase capacity, whichever comes first. Otherwise, I believe they will lose a lot of players. Maybe some players will return later, but many will simply move on. Fortunately, I am often able to play during non-peak times, but that is not the case for most players.
