Going to just point out Synx's experience in terms of PvP.
Here is Synx telling everyone how op Prot Warrior is in LK... with a shadowmourne
Here is Synx's warrior's match history:

Solid 1.4k experience, as a Warrior (one of the easiest and most OP classes, according to himself)
Here's his main:

Yes, a warlock. Why don't we take a look at arena ladders now:

The most bracket around which PvP is "balanced". Let's see hmm...
2 warlocks, 1 warrior in top 10.
10 warlocks in top 50 (that's 20% for those following along)...
We see our first hunter in the ladder at rank 50.
Isn't that interesting. The easiest, and most OP class doesn't have a single player in the top 50 (excluding the 50th rank). I wonder what the reason for that could be. But wait there's more.
In all the Blizzcon's hosted, there has only been one Hunter that has won.

They played PhD (One could argue this was partly because DK's were ****ing op, but I digress).
You would think that if Hunters were so easy and OP in MoP, they would have won Blizzcon for it, but nope. LSD reigned dominant.
So Synx, please stop talking out of your *** and do some research. Feel free to play Hunter here and get a feel for it in 3v3. Then you'll come to realize just how **** they actually are.
