So long World of Warcraft
It's been a completely original and fun MMORPG (defn.) experience, but the recent series of patches have caused more problems and bugs than they've fixed. Blizzard seems bent on adding new additional "buggy" content w/o properly fixing many game-breaking and faction unbalancing issues in existing content.
Additionally, Blizzard has most definitely not listened to the player community regarding tweaks to the various talent trees. This has resulted that, for the vast majority of character classes, only 1 valid "cookie-cutter" talent build exists, thus defeating the original intent of the talents themselves. Blizzard really had a good core game, it's a shame that mis-management of the ongoing WOW service has resulted in a continuous degredation of the player experience.
