My opinion is get rid of solo.
Going back to my first points it will force people to have more fun and find solutions other than hiding.

Lately it seems like all entertainment media is trying to be the manic pixie dream girl who exists to take us by the hand and bring us out into the open as it spends more and more nights of unprotected passion with social networking services. Ten years from now you won't even be able to sit out on your balcony and read a book without some spring-loaded device on the spine launching a pop-up over the page letting us know that some loser in Cincinatti is also reading the book and would I like to chat about it.
Getting rid of Solo is tantamount to getting rid of every single player who happens to be an introvert, or who simply doesn't want to have their gaming involve other people for whatever reason.
