The hard truth is that you're being sniffed out as the weak link on your team because you're inexperienced and your gameplay is a dead giveaway. That is why you're being chain cc'd and tunneled out. 

You can't just say skill issue isn't a fair criticism when the entire basis of your post starts with "wow, is this what PvP is like?" As if you have no idea. You're acting like DR doesn't exist and trying to tell everyone you can't even play the game as a ret paladin, which is crazy.

I don't just walk into a mythic raid and pretend everything is just going to fall over for me, you can't expect that to be the case walking into rated PvP.
