I think two things also contribute this situation:
1). Like me, a lot of players saw an opportunity to try Highlander Warrior for cheap for two weeks, since it had so many nerfed cards.
2). Many of us have played metas were aggro Hunter was dominant, so we found ourselves being attracted to playing something different.
The first three golden heroes for me were Warlock, Mage, and Hunter, so I have played a lot of Hunter before, especially on other accounts, since Hunter has often had good, budget-friendly decks.

About a month ago, I asked what kind of deck I should make for Standard for a new account, and the best advice I got was:
But I decided to skip playing Hunter, because I did not want to spend much time playing that deck on a new account.
Today, I decided to play Hunter on my main account and I can already tell that the deck will be easy-mode to Diamond Rank 5.
I am currently 14-2 with Zoo Hunter. I botched one game by not playing Saddle Up when I should have—turning an auto-win into an auto-loss. And I loss one game to a Druid when I risked overextending with the hopes of playing Saddle Up on the next turn, but I was punished by a devastating Swipe. I made the same decision against the next Druid, but I won that game (see the following pics).
