I would like to add some comments on the LFR tool. I think that its impact will be detrimental but its effect will be on the long run. My concern is for new players. Real new player (if they exist), they do not need a guild for leveling, nor PVP, dungeons and Raids. These new players will experience all the game has to offer without the hassle of a guild.
I personally don't PUG nor do I know what LFR stands for unless you mean ( LFG, lets say FL, must know this, must have that ), I say go do it yourself. if your so particular. And your right. You can have a good time on WoW without putting up with other people, especially, Vain, selfcentered, narcissistic Charlatan's who think their better than everyone else. And your right, there are no new people. Every person I know on WoW has more than 1 Toon, I have 10 on 1 Server, 7 LvL 85's, alts mostly and thats what I use them for. I don't care to run them in dungeons or raids. Additionally, I can go back and have fun in past content. It's now a cake walk through Steam Vaults with a LvL 85 DPS Pally. Advice, find a guild that will beat the crap out of you just to teach you the ropes, help with your talents and spec and yet too is friendly. We all make mistakes. No matter how long it takes, stick with it and communicate.
