Oh holy shit. Thanks for that!
Where was the meltdown part of the thread when this was all revealed?
Why would there be a meltdown?
1) Priest is going to overheal in many cases and in some cases be at 30 health which means that in many cases the extra Heal will go to waste. And if you are doing a lot of wasteful heals then the card is not worth it to use. Maybe in a Velen/Auchenai deck but in standard Priest deck it's meh.
2) Warlock it doesn't really do much. You still just get one card.
3) Hunter has the worst upgrade. While most classes got their effects doubled, they got a buff from 2 to 3 damage. Not at all worth it to use in Hunter decks.
4) For Warrior it's good because Armor is never technically wasted. However, for this card to be worth it over Shield Maiden you need to get 3 activations of your hero power off.
5) Mage benefits from the hero power quite a bit however any time you kill a minion with 1 health using this new hero power... the bonus is wasted. It's better to just use Fallen Hero as it's faster and you get the 2 damage ping when you actually need it.
6) Rogue is looking like the worst class going into it new expansion IF Inspire is actually a thing. Their hero power is anti synergy with the whole mechanic and thus their improved hero power is actually the worst. Inspire mechanic benefits hero powers that you can spam... having a 2 durability dagger sort of goes against that line of thought.
7) Druid probably got among the better changes because you get both double damage and double armor. Still not quite amazing enough.
8) Shaman's change is interesting because you can choose the totem and you can have duplicates. That still isn't that great because other classes are getting double effects of their hero power. Who cares if you can get one extra taunt out when Paladins can get double Recruits out instead?
9) Double recruits means easier ways to activate Quartermaster but the hero power scales poorly in the late game because there are only 7 minions on the board at the most and you don't want to fill it up with 1/1s.
