I understand that, which is why it's very disappointing for folks like me, who don't participate during a certain time frame.

While this game isn't a PVP first type of game, you should be able to queue and fight and continue to work on progressing your rank at any point and time during the season. Missing out on this time window and then being screwed for the rest of the season isn't how PVP games operate. It really narrows down anyone who wishes to participate.
