Perks that are mainly solo bonuses are one of the reasons I'm not that interested in WoW anymore. All those guild perks makes me feel like characters without a guild - and a high level guild, at that - are second class characters.

Given that I take my sweet time choosing a guild, and won't ever get in a guild just for a few perks and a shot at game content - I will only join a guild if I can legitimately think about most of it's members as actual friends - all this makes me feel like Blizzard simply does not care about players like me, for whom guilds should never be just a convenience thing, but instead a group of like minded players that are care about each other and want to face the game together.

Not to mention that the current guild leveling system puts too much power into the big guilds, and more specifically in the hands of guild masters. As said before in the article, starting a new guild, something that was already hard before Cataclysm, became even harder. Worse yet, what is to prevent an unscrupulous guild master that is leaving the game from just kicking everyone else from the guild and selling control of it? I believe a lv25 guild would fetch a pretty penny.
