I really think Blizzard missed an opportunity. In Ulduar, you have this large area where you can knock down towers and avoid laser-shooting spiders. They could have done a whole "Mario Kart"-ish event with speed boosts and jumps and barrel throwing monkeys. But, players don't really like being in something to fight. We would rather stand on our feet than push buttons 1-4 in some sequence. Still, I think of the missed potential every time I go into Ulduar.
