I don't think that is going to change enough. Most decks can't heal that much, that fast.

My guess is that is going to cost 4-Mana again, but Steal 5 Health from the opponent. Which to me kinda kills the card, but I doubt they will just change it to deal 10 damage with Lifesteal, it would be way too gentle of a change for part of Blizzard.

How does that kill the card? 4 mana 5/5 deal 5 is still a really strong card, that's a Pyroblast every turn with a body attached when you bounce it. 

I´d rather for both options, No bonus + 1 more mana

It's going to remove interaction with cleaving minions the reason being it makes every other card besides hound and the dog useful. They want other archetypes besides wait till hand buff, get 18 18 minion cleave game

I know everyone is screaming cost nerfs, and for ABJ and Sharpshooter I see it, but I also see a nerf for Order in the Court which removes the innate card draw. Would make playing it a riskier proposition for aggro decks because you can't follow it up with a free Lightray.

yet again shaman dodged buffs

Blizzard is making sure, that the only playable wild decks are aggro.

Blizzard instead of HARD nerfing Pirate Rogue and Shadow Priest, they nerfed Firemancer Flurgl, so funny

 Shudderwock Shaman is not playable? Nice joke! :D

Also Big Shaman is at least "playable". Is it a good deck? I am not sure. But "playable" is it for sure.

The wild ladder it is full of totem shaman and reno shudderwock shaman...
This deck need nerf like pirate rogue and priest

Never encountered a highlander Shaman at D5-D3, failed miserably when I tried playing it.

That sounds more like you're bad with the deck or in general than the deck archetype being bad as a whole. D5-D3 isn't much of a sample size either. 

Surprised that out of all cards they picked Order in the Court. I expect all 3 cards to be nerfed by one mana.

And by nerfed you meaning increasing the mana cost by 1.

While this is almost certainly how they will nerf it, a much better nerf would be to not draw. The cost of Order in the Court almost never matters because it can always be followed with a free Lightray
