I play as a Guardian druid. Let me take what you said, but change it and make it make 100% sense.
"Tanking doesn't require skill, but knowing which abilities are good and which are not for certain situations is 'required'. You can actually lose out on extra dps if you don't use the right attacks. MUCH more fun than the old system." Notice the only real change of importance: I replaced aggro/threat with damage/dps. Seeing number is more exciting, that's why all tank abilities do damage; devastate was just a lot more fun than sunder, even though it's the same damn ability.
