Now that Cata classic is almost over I'm going to say its a pretty good expansion
It doesnt deserve the bad reputation
Sure the DS raid is not as a good as the previous tiers but when it comes to gameplay, Cata is far more enjoyable for me than TBC or Wrath. The classes feel more polished and are actually fun to play

I'd say Cata, MoP and Legion are my favorite expansions. I can't go back to the TBC/Wrath clunky slow pace, the classes feel so boring in those exp

I can understand why people like Vanilla but its a whole different game. TBC and Wrath were good and enjoyable back when I was a teenager but they are nearly unplayable now.
