They just say what they heard from Blizzard, which is ladders will most likely 4 months long.

I think we've all read the release notes lol they were talking about shortening the ladder times but never confirmed that is what they were doing. Ladder on D2 was 6 months if I remember correctly. But I feel a lot of folk try n say it with such confidence with no real substance other then wishful thinking but passing it as a confirmed fact

I think 4 month ladders would be perfect. 6 months is too long. 3 may be a bit too short, but i think many of us love to rush of ladder reset. 3-4 of them per year would be ideal (versus just 2)

I mean no argument there, but at same time 6 months gives those who aren't every day players a chance to hit ladder too. But I'd rather it be 3 months tbh gives more of a rotation but 9/10 the top ladder are gonna be bots but it sucks when PC folks hop on other consoles etc just to take over ladder too
