Actually, what you post should be the reason to keep him in the position.
You are not factoring the game's age and the (very real) burning out people experience, you are even dismissing it from your opinion. His solution to the game's age is accessability, which is actually making the game last longer for a lot of people.
Or what, you really expect the game to be as engaging as it was in BC? If it was true, people would still be in Outland, happily doing Netherstorm quests and going for their 4th alt with Loremaster of Outland. The demand for faster end-game content would be non-existant. And Nobody, ever would utter the word "I am bored", especially considering how awesome BC was in the minds of so many people, people would just go and do Shadowmoon quests in all their alts.
