Warmane xmas holiday events are the same, why?

Titile.
While we appreciate all the effort and such, why we get the same events as last year? With the exact same rewards?
Rewards mean nothing for me at least but why we gotta do the exact same tower defence and the exact same battle royale on the exact same BG along with the exact same rewards as last year?

Cause new players didn't do the event last year.

Even on the Brewfest event, you could not get the mount and you have to try it again the year after, or the achievemnt of the clothes with the event coins.
