There are so many people in this thread that are so quick to want to defend their beloved current style that they aren't thinking about what the OP is actually saying.

Tanking HAS been dumbed down. Massively. Currently if you have your tank stance turned on, you can roll your face across the keyboard and hold aggro. As a 80 DRK in any dungeon I can spam Salted Earth -> Bloodspiller and hold aggro on all the mobs without any worry of resource or threat management. I can then throw in random things like flood of shadow, abyssal drain, and Quietus. But outside of trying to maximize my damage output, there is nothing else to think about.

This is a huge mistake imo. It's the exact same mistake that companies have been making with healers. By removing resource management and tactical usage of abilities in favor of spamming everything you have whenever you like it is taking away the ability to learn, grow, and a reach a higher skill level. Sure, for new tanks/healers? It's never been more accessible. But what do you have to work towards? How do you get better? How do you push yourself to feel like you are better at your job than others? Right now, you really can't outside of just trying to do the most DPS you can. And if that's going to be what separates your skill from someone else, why not just play a dps class?

It's this kind of dumbing down of tanking and healing that leads to more and more of the experienced people that love those roles stepping away from them and more and more of the braindead people spamming holy and not using cooldowns to come in. If that's what you want in your runs, then go for it. But it's really a shame the more the skill ceiling drops.
