It doesn’t happen very often, but Blizzard have announced some balance changes, nerfs, (buffs), coming in October. Probably to try and add some balance before the Last Call Championship matches and Blizzcon Finals.
There has been a lot of backlash from the community for some blatantly overpowered cards for some time. Yogg, Call of the Wild, Tuskarr Totemic are three of the worst offenders and they are all being hit by the nerf hammer.
This is the Charge nerf/card balance change for Warrior coming in October.
As you can see, the car text is changing from: Give a friendly minion +2 Attack and Charge, to Give a friendly minion Charge. It can’t attack heroes this turn.
How Will This Change Affect Warrior?
There are more than enough Warrior builds that I personally will not miss the crazy OTK decks that relied on this card. It was fun while it lasted but bouncing 60 + damage off your opponents face is a thing of the past!
Hearthstone Developers Comments
Here are comments directly from the developers about this change to Charge:
While we enjoy seeing players explore combo styles of play and will continue to support it in the future, we’ve seen in the past that the ability to give Charge to minions that don’t normally have it has been particularly problematic and also heavily restricts future cards. We’ve redesigned the card Charge in a way that provides opportunities for minion combat, but does not enable strategies that intend to win without allowing opponents to interact.
