Cata was fine. 80-85 was generally fun(Uldum being tedious only after the first time you did it, and really fun the first time). The heroics were actually challenging(Like in TBC). It's not my favorite expansion, but it was. The first set of raids were actually really good. BWD and BoT are not bad raids by any measure. I enjoyed them more then I enjoyed Naxx redux by far. Cata gets a bad rap, but overall it was a good expansion.
Of course they are orgional, but i mean that they have used up most of the good ideas so far. There maybe a few more good ideas for a new expanison, but it seems that it will start to go down hill from pandaria.
Fully agree. I have been playing WoW since BC and thought that ALL of the expansions so far have been good, but im curious on what sin the future. Pandas? what next, revenge of the kobolds?
