Since introducing the ladder season lock and roll process we’ve continued to monitor the length of the seasons and our previous desire to see seasons last around 3-4 months. After gathering data for several seasons now we’ve come to the conclusion that shortening the seasons will better match how most people are playing the game, and support a more dynamic, rewarding, and vibrant ladder experience.

Beginning with season 4, we’re looking for each ladder season to last around 2 months.

We’ll be providing further updates regarding the roll to season 4 in the coming weeks.

Looks like it might be an issue with a lot of people just not laddering,inflated bonus pools. Wouldn't mind it, frequent rotation of maps would be okay and fun (as long as they get the crap ones out). This might also solve the problem of people getting stuck in a league mid season.Sounds pretty good to me.

But I wonder how the grand master league will function , seeing how the league is closed for two weeks, thats now a significant portion of the season.
