I think Moroes is about as bad as Purify; why aren't there petitions about that one?
Priest got a couple cards that are going to be used in decks. That's more than some classes got.
Seems like people are asking for Blizz to turn Priest into just another Curve deck with over powered early game minions.
If Priest players want that style of game play, pick up literally any other class.
1) Moroes is a neutral card. Neutral cards tend to be weaker than class cards anyway.
2) It being neutral means that it does not hurt or help one class absurdly more than others.
3) It doesn't take up one of the three crucial class cards. Pompous Thespian is a meh card too but no one is complaining about because it's just a neutral. If Prest got that as a class card then people would be upset too.
4) Moroes is STILL better than Purify.
5) Purify is given to the worst constructed class in the game at the moment.
6) Purify is a common so it's going to mess up Priest Arena too. And Priest is also the worst Arena class.
7) The whole design of the card is non sensical. The card comes with a draw back yet isn't cheaper than normal for a drawback card. It's not in line with how they have costed cards.
8) The card is significantly worse than other class/neutral cards that do similar things (ie. a 2 mana cycle). Worse than Flare, Slam, Battle Rage, Under city Huckster, Novice Engineer, Loot Hoarder... all of which draw for 2 mana without a drawback. Even the draw is conditional.
9) Priest already has a 0 mana Silence that they can use to target both friendly minions AND enemy minions. They also have Power Word Shield that buffs your minion and cycles for 1 mana. Not only is this card extremely bad... it's also redundant and boring.
I looked over all of the class cards and I think only Savagery is probably worse than Purify.
And just because people want better cards for Priest or they think Purify is a joke doesn't mean that they want Priest to become another curve god deck.
