With all the bunch of lore characters involved in the game i believe the Cata will really hit the spot this time.And with all the changes made i think this could be really interesting and great expansion....
We have Cenarius and Malfurion returning,Cho'Gall ,Ragnaros, Neptulon, Al'akir,Therazane,Thrall....and bunch of interesting lore characters.
+ 2 new classes...+ a little bit of Maelstrom and elemental planes....and who knows what we can expect in later patches.
This really looks like a great expansion,i just hope they don't ruin it....But storyline can't get any better
