It's still shows a very different result to what we see today. You seem to be failing to grasp my point that Wrath wasn't loved as best expansion when it was still fresh in everyone's memories. The polls that featured Wrath show a very different result to the ones that are taken today:

This is the entire point of my argument, which is something you fail to be grasping. Wrath was unpopular amongst the long time raiding community. It coined such phrased as Wrath baby and is generally paraded as the banner for dumbing down and quick irrelevancy of previous tiers. This was the xpac that gave us rehashed Naxx as the first raid, Ulduar is largely considered one of the best raids of all time, however ToC was seen as lazy, short and boring. ICC was a decent raid, however the time we had to live with it made us never want to see it again.
Roll around to present day and we see a sharp rise in the love of WOTLK.
Consistently (in the past) when asked what was the best expansion, TBC has been the winner. Today Wrath now takes the crown.
Believe whatever you will, but Wrath was not popular at Cata release. It may not be as unpopular as Cata is today, but it was not some Golden Egg of an expansion that was loved by everyone since time immemorial.
