If you've been playing a lot of competitive Hearthstone, you might have a few opinions about some of the decks. One of those decks might be the rogue deck, and you wouldn't be wrong for thinking it's at least a tad overpowered. The Hearthstone podcast Turn2 recently interviewed Hearthstone developer Eric Dodds, and he confirms that the team feels that the rogue deck is incredibly strong right now. In particular, the Defias Ringleader card is a noted culprit. If you play the Defias Ringleader in combination with another card in your deck, the Ringleader summons another minion: the Defias Bandit. Seeing as the Defias Ringleader costs only two mana to play, and playing it in conjunction with "The Coin" counts as a combo, it is possible to get both the Ringleader and its Bandit minion on your first turn of play, if you happen to be going second. This is a devastating opener and has been singled out as one of the reasons the rogue deck needs to be reined in.
On the other end of the scale, Dodds also stated that the team recognizes that priests and warriors feel a little underpowered at the moment, and they are looking into ways to improve their performance in the game. Most of it seems to come down to finding the right balance in numbers, which will hopefully be a relatively easy fix. You can listen to the entire interview on Turn2, and save a moment of silence for the Defias Ringleader whenever the updated Hearthstone build is released.
