Cata is much better than vanilla and wotlk ever were, think back to how things were then and don't just linger on the good things but think how horrible some aspects of gameplay were especially in vanilla and early wotlk... wotlk got pretty good with ICC in the end though (sunwell era being my all time favorite).

If you're tired with the game take a break, it's hardly reasonable to assume that one game can keep you interested for years and years, we already have one whine thread why make another?
