I can't believe there isn't a thread for this yet, especially since the game just went into open beta in the US.
Anyone here play it? If so, let's discuss it here! What hero do you hate the most? Is there a hero you main? Your favourite cards? Best wins or worst losses?
I like to play Shaman myself, and can get to around rank 20 with my deck, but I don't have any legendaries or really good cards, so I don't seem to get really far. The one class I can't stand are mages. Holy hell are they annoying to play against! They have AOE spells for days and then can rudh you to 10hp judt to use pyroblast. I think they need to remove that card altogether, just a bs way to lose...
Hunters can also be annoying, though I don't seem to have much problems with them as of late. My Shaman deck is fairly anti-rushdown, so I don't often lose to aggressive Hunters anymore.
I lost an arena game to a Druid who used Innervate, turn two to summon their 4/6 with taunt. Then he used Mark of the Wild twice on it. Insane! I lost a close match to a Mage that had Pyroblast...

My BF and some of his friends are in the beta and they like it so far. Not a big fan myself though :/
