I think 3 month was a better cycle for the players. 4 month is just too long and also content creators run out of things they could say about the game now.

In my opinion SE tries hard to rework older content and make the game better as a whole. But on the other side this means lackluster and nothing to do for all long time players. I also think that the game is in a bad state right now, regarding to fun and new good content.

3 month cycle means 4 patches in one year. And 4 month cycle means only 3 patches in a whole year. That IS a big difference.
