My cousins are really into this game, so I had a chance to play it over Thanksgiving. I made a troll rogue.
Pros: The controls took a little getting used to, but once I did the fighting was rather enjoyable. I actually had to pay attention to what was going on, rather than point and click. I also liked the menu system for all the skills. (My cousin had a mod so all of his 50+ priest skills were on screen at once)
I never got to see a raid, but those sound epic. Also if loot becomes easier to get in BC, that may get me into it. I like how the characters look when they get all their gear.
Speaking of looks. Beautiful game. All the character models and environments I saw were great. It definatly helps me get into character.
Cons: One of the things that really put me off though was the traveling. Like I said, I'm short on time. I want to play my game, not sit back and watch a bat's ass for 20 minutes while it flies across a continent.
Also server stability was a big problem. In the short time I played with my cousins they were kicked twice and 3 of the servers were down.
Verdict: Not really for me. It seems like a game that really favors the hardcore gamer. I just don't have the time to put into it for it to be worth my $15 a month.
