We could use another event of double exp, just to break up the monotony. Runescape had those moments where double exp times were announced ahead of time of the event itself, so I wouldn't see a problem of people preparing for this kind of event anyways. With the feasibility of such an occasion, at least it could be implemented at the flip of a switch, so why not?
As a community of players, even with a low amount of players anyways, weren't there times we had this occur also with a low playerbase? Maybe we could use something to play for.
