Does tanking carry more responsibility than most?

I disagree with you, tanking is also a throughput role, but its throughput is focused around enmity. If a tank can't achieve the highest amount of throughput in enmity, the healer inadvertently will, and cause a wipe. Yes there is skill involved in how that enmity is thrown around, but that can pretty much be said of any class/job/role. In the end, all roles boil down to the same goal, which is ultimately achieved simply though different mechanics. That goal is to maximize positive effect while minimizing negative.
