Some sections of the forum are rarely used like star wars the old republic and Diablo II and also League of Legends strategy and guides/ WOW server development. It would be nice to see it cleaned up a bit and make the forums shorter so you don't have to scroll down as much. Sorry to the people who use those sections but I think it's time to get rid!
I do agree they don't have much activity, and probably only really need a subsection instead of a whole section. If its getting in your way and you don't wanna have to scroll the whole way down, you can always click the arrows on the far right of the title, which will collapse them, like in the picture below.
