I honestly think Wild is in a decent spot right now, partially because of Demon Hunter.
Before AoO came out, Quest Mage was borderline untouchable. Since AoO (and the quest nerf) you can play other combo decks, or slower decks in general without auto-losing to the (at the time) most popular deck in the game. The aggressive meta keeps Quest Mage in check, it makes playing pure counter decks relatively viable, and makes for more entertaining matches in midrange strategies.
In all sincerity, I find the current Wild meta much more fun than the previous one, where 4 out of 5 opponents played almost nothing but spells (such as Quest Mage, Reno Mage, Reno Priest and Jade Druid). If there's a minion in play, there's something I can interact with, and where I have to make decisions. As much as I hate Secret Mage by now, it's at least engaging to play around secrets, or leaving secrets in play to deny Flakmage comebacks.
To me, the worst games are those where one player does nothing but removal spells and board clears for 6+ turns. I love minion trading and fighting for the board, but when my opponent has NOTHING in play and I can't even chose to attack anything but face, it's just boring and I wish I was playing something as "interactive" as Mill Rogue just to punish that endless stalling.
