Yesterday afternoon, I read a great article by Ambrosine on I Like Bubbles. Her post focused on why some Paladin tanks ask a Discipline priest to not bubble them O_0
Yup, I do understand that there is an issue of the bubble actually being “too” powerful, scaling too well, and preventing any damage from actually getting to the tank, and in turn not requiring any heals. This effect, causes the paladin to not regain mana from Spiritual Attunement. This, apparently, is what these tanks are complaining about. Now, to be fair, most, if not all of these Paladin tanks that complain are found using the LFD system, they may just be starting out, and are running 5 mans. However, if you actually plan to tank, and fulfill that role, then it would be best for you to learn your class.
