These first three days of expansion I've been playing druid, rogue and warlock (initially Hand Lock, but had to go zoo or wouldn't have a slight chance against galakrond shamans). Now I've found the only deck that I can actually win against galakrond/quest archetypes quite easily and, look, it had to be another cancer: the new pirate warrior. The deck is simply insane and even if you didn't get a good mulligan at first, you still have many possibilities to apply preassure against your opponent. (SMOrc 'em down, baby!).
Spotted a shaman player. You might not agree or understand the reason for these posts, but the blizzard devs have listened and that's what counts. We got some good news, help is coming. Balance update Inc next week. So you shamans out there get your legend asap while you still can!
