Kitru might be pedantic, but in this case he's entirely correct about the difference between eHP and mitigation. Any tank seeking to better understand their CDs and ideal use should be concerned about the difference and apply that knowledge to in-game situations (including group tactics) to gain an advantage.
And seriously, GFY on the "convenience" argument BS. You can say it's not laziness, but it 100% is. Using a controller for battle content in an MMO is lazy. Period. Being lazy is okay, just own up to it and don't pretend you're something you're not.
