Should i start wow again?

Same thing happened to me, only with Runescape, i played it for a really long time (about 4-5 years) and then it just started losing it's grasp on me, i don't know if it had to do with me growing up, or if Jagex just f*cked it up. Either way, forcing yourself to play a game you don't like doesn't work in the slightest. If you think it's a good game and still have "the urge" to play it, by all means play it. But if you're just fed up with all the BS, don't force yourself to try to like it, it just doesn't work.
