Clearly watch posts are strong. I doubt they will be nerfed or even if they are probably very lightly. But from what I can see, one deck is quite mean with them. And that's basically a Value warlock deck.

Now the thing that makes this deck quite annoying is that it can match up blow for blow with all the control decks. It also can just steam roll some decks with it's midrange capabilities. I'm pretty sure i don't need to go into deep explanation from what you can see with the deck. But its a lot of hiding behind your watch posts, clearing board, and setting up for your late game cards. C'thun cards are good activators for cascading corrupts (c'thun himself can wipe off a priest who is trying too hard to cause a 30 minute game). 

So far i've not had any games where things just felt bad unless someone completely out lucked me. I think the only thing that can be a threat is hyper aggro, but you do have cheap minion clears and mor'shan/far watch posts to slow them down.

I think a variant of this deck will be at least A tier, maybe not S tier, but now a days what even is S tier :p
