I agree. Now Priests can execute some crazy Frothing Berserker combo too. Might be a problem in the specific combo decks, but in normal Priest decks, I reckon it's not enough to challenge Auchenai and Piloted Shredder. Also depends on other upcoming cards.
I suppose Frothing Berserker is the closest thing to compare it to (when we disregard Light Warden), but i think that would be wrong comparison, since Frothing combo will never be without a charge and u cant charge this priest card, so it will have to be played very differently.
The reason why ligthwarden stopped seeing play even pre-GvG is because it was effectively a 1/2 for 1 in too many cases. I believe that the same will be true for this 3/5 for 4. The stats just aren't good enough these days for what the effect realistically gives you (not even close to the power level and consistency of frothing berserker in patron decks), and it is a lot harder to cut cards in priest than in other classes. Auchenai soulpriest I feel is just better than this card on principle, and even that card is getting cut in some priest builds to be more consistent. These are my initial impressions anyway. We'll see what other cards are released with the set.
Light warden's ability is good, but the whole shitty 1-drop thing doesn't give it a place in priest decks, which tend to be midrange. The decent body on this (more importantly the 5 Health) passes the vanilla stats test and can be played on curve without much drawback. Really great card.
I'm a priest only player and i got legend a couple times with the class.
Really like this card. It's very similar to Auchenai Soulpriest, you use your hero power to gain +2 damage but you can't split the damage, like auchenai does. However, this card has the potential to grow in the late game and make some crazy Wild Pyromancer + Circle of Healing turns.
