I love it.
I am have yet to even do an instace in the outlands, and I will never raid. My brother in law and I have an arena team. We both have pretty much crap gear, and we just got our 2v2 rating (which was at 1100) to 1800 and change. We won 92% of our fights this week. We are now working together like a well oiled machine and there is no combo that gives us a hard time over and over.
I have no skill when it comes to twitch, I over compensate by by not being able to react fast and having poor gear by knowing (through study and a lot of practice) what every class and every 2v2 combo is capable of. We have to outsmart the other team and constantly change our tactics (unless the other team is just retarded and doesn't know how to adapt). We usually fight the same teams over and over in one night of the arena, so we have to constantly stay one step ahead of them by not letting them adapt to us, and us constantly adpapting to their strat.
People that raid all the time and have the best gear doesn't equal them being smart, it just equals them having way too much time on their hands.
But I agree, the BGs are a huge grind. But the arena is how pvp was ment to be (at least in the 2v2, I've never played 3v3 or 5v5).
