I'm gonna tell you a true story, my friend and I were playing against a warrior and monk healer, I was enhancement shaman, and he was a priest disc, I got cc'd about 90% of the time we played that arena so I told my friend I got pissed of and went to make coffee, the time I came back, I was still cc'd and my friend jumping around like normal.
If you gonna give 2 classes, warrior and monk, so much cc that they can have me cc'd pretty much whole fight, then can't enhancement shaman atleast get a 2-3 sec stun?
You do realize that this doesn't really mean ANYTHING, right? Your comparing a team setup against an enhancement shaman here, aswell as using one example to make this statement. If you'd show us about 100 videos of different players using the same setups with a recurring pattern of this event, it might add some value to your statement.
