It seems strange to me that you couple content additions (new dungeons, quests etc) with character balancing in your patches. Content takes a long time to develop, with the time between 3.0 and Ulduar having been what, 6-7 months? By coupling character balancing changes with the content changes, yu end up waiting 6-7 months to balance over and under powered classes, when many of the changes involve modifying a coefficient, a base dmg/healing/whatever amount, or a cooldown. I can understand that some balancing requires development, but there seems to be a clear divide in most cases between the work required to add content and the work required to add new talents or spells. Couldnt you do seperate patch iterations for class balance and content addition? If you did that, wouldnt it allow you to react more quickly to imbalances without causing the feeling that too many changes occured at once that was felt in a previous patch?
