Ya I'm feeling the same way. Last night my wife and I did arenas and I was getting pissed off. Most of the teams that wooped us had a priest in the team, their bubble is so damn OP it's ridiculous.
As far as the rest of the expansion, I've just been bla with it all. I've been playing my level 70 twink Druid most of the time. Less CC's = More Fun.
Without a good group of friends to play with, and the challenge of raiding, there is very little content to keep high level characters busy or interested in Cata. Lucky for me I have a good group of friends I play WoW with.
PvE is a great deal more difficult than it was in Wrath, this being good or bad depends on your perspective. I like the challenge and have managed to pull my DPS up substantially. My biggest complaint is how much more difficult Blizzard has made healing. There werent a boat load of people willing to heal in Wrath now there are even fewer. Yes a good healer can manage to make it okay but there are no margins for error in the group and the healer has no ability to compensate when something goes off track even a small amount.
PUGs are proving to be a complete PITA waiting 40 minutes for a group that wont work together to save their own grandmother. To be honest the PUGs are getting less troublesome as people start to get over geared but there are still long queue times.
Start a Goblin or Worgen? Sure and enjoy the new low level content until you end up needing to grind 60 to 85 through all the stuff that you have already seen
not fun IMO.
Ive said it before, I like Cata and most of the changes that Blizzard has made to the game but the content is very thin compared to other expansions.
