I agree with both. It is a bad deck, like freeze mage, in that it is non interactive. After they have said more than once they want more interaction. (Moving Conceal to Hall of Fame and maybe as part of Ice Lance / Power Overwhelming move and other times.)
It, and Quest Warrior, are the biggest reasons I've gone to Hunter. You have to be aggro to have a chance. (Or I guess freeze mage or something else yuck. Or Paladin which I am now seeing the most. Boo Equality and Brawl. I know Equality is only part of Muloc Paladin, get possibly 3 Tyrion Paladin and Lightlord, etc but I hate it and Brawl after several months of never seeing either.)
It's much rarer to see Quest Rogue because the meta is so aggro. But I do think it should at least be nerfed to 4,4 if cost is 4. Much more removal and minions could deal with. I think going to 5 cost would be rougher but I'd be ok. I have it but didn't win with it and don't like playing solitaire just about for 4 turns or so to see if I win. I think it's bad that mid cost has nearly no chance against it (other than Paladin or I guess Warrior.) It was a bad idea. And while I've found my solution in Hunter. Playing Shaman, which I'm glad we've moved away from ShamanStone, shows me how I don't like this meta. I'd prefer meta before w Pirate Warrior as king by a lot. Even without Golakka (I run two in my Hunter also helps vs rogue) you could go double acidic swamp oozes, etc and beat Pirate Warrior. But double Golakka in a mid cost won't beat Caverns.
I think it was a bad idea, build concept, on their part. As is unlimited Die Insect hero power reward. As is Take Another Turn and an infinite dmg combo. I like a lot of the new stuff. Like Elementals. Finding 'the right' mix for Shaman has frustrated me, but Elementals are new and unique and cool concept and cards. Several things as stated have disappointed me about new set. As someone asked on Battle.net forums. Why so many new people? Someone said what i had in mind about it. - Shows you the game had been mostly fair up to this point / a lot of people who hadn't felt strongly enough about things to Post to Blizzard, decided to. Including me.
