We recently found out that an upcoming patch would revert a fair few nerfs that some cards have seen, and the first candidate has been revealed!
In a strangely-timed tweet, it's been confirmed by the official Hearthstone account that Sludge Slurper will see a return to 2/1 stats. Perhaps this will be a boost to Shaman's recent flagging performance?
In our next update we'll be reverting nerfs to a few select cards, these will primarily be cards rotating into Wild. However, included in this update will be Sludge Slurper, who will revert back to 2 Attack / 1 Health.
