I didn't say it was the best ever. Also, it isn't a great expansion, but raiding is one of the top points in it (except for shitty Dragon Soul).
You are listening too much to the negative things people has to say. If you want, make a poll and you will see that 65% of people at least will tell you they enjoyed the expansion. While 35% is a HUGE percentage for people not to enjoy it, but the forums usually mislead you to think that it is otherwise.
Let's not turn this into "this expansion is better/worse than that" because this isn't the topic of it. We already know that WotLK was an overall better expansion. If you want to make that poll about whether or not people enjoyed Cata or not though, please PM me the link to the topic and i will participate. I am happy to be proven wrong, because I know I won't, since I did it before multiple times.

The animation is actually kind of fitting in my opinion, but I see your point.
