ZA/ZG was brought out to bring a mid-tier ilevel instances to people who needed an extra boost in current raiding content. Of course they aren't releasing content fast enough when the mindset is HURRY HURRY HURRY. Gear is too easy to obtain now as opposed to Vanilla where you could be in MC for months at a time, and not have full tier 1 gear. There isn't a balance between the 2 that has been struck yet. Heroics have become a joke, yet again, now that people are geared out. No one wants to take the time to CC, or listen to strategy on a boss. It is the PLOW THROUGH FPS mentality that hurts the game.

I should also add, that if you are not happy with the content of WoW then NO MMO will ever satisfy you. Blizzard is the best at these types of games, and are far above the quality and quantity of content available to players.
