I stopped playing because most of the people I know don't play ladder. I play for the social experience.

On top of that my hands shake and I can not really accurately click on a lot of stuff. I will still play some of the Co-Op stuff with people since it is not as demanding with the attention span or speed and you can pause the game if you really need to take a break for a minuet. Not really interested in the competitive side of the game.

This is for when I did play.
I did not really care for everything being a choke point map for custom games. Its like everything needs to be a tower defense with no thought for strategy of how the game will flow or flank maneuvers. That's not what makes RTS games fun for me.
