Immunities are powerful things. Divine Shield is a spell that provokes very heated responses from anyone who has faced a paladin in PvP combat and draws the envy of nearly every class for its incalculable uses in PvE content. Even though our damage output is cut in half for the duration of buying wow accounts the spell, being immune to all forms of damage for eight seconds is incredible.
The devs, however, thought that eight seconds of damage immunity wasn't enough and gave us the wonderful talent Unbreakable Spirit. In short, US allows you to reduce your Divine Shield, Divine Protection, and Lay on Hands cooldowns by 50% simply by spending holy power. As ret we're usually bursting at the seems with the resource, and spending it is in our best interest regardless of whether we spec into US or not, so this talent basically allows us to have DS available every two and a half minutes.
Now, I know what you're thinking: if you're in a position to buying wow gold need an immunity every two and a half minutes, you must be doing something wrong, right? Well, there's another use for our bubble that Rossi discusses in his article -- preventing debuff applications.
Say you're just starting out on heroic Jin'rokh and your healers are having a hard time finding enough magic dispels to cleanse Ionization from everyone in the raid. With DS, you can prevent Ionization from even touching you. Not only will this help your healers immensely, but you can also remain in the damage-boosting puddle for its entire duration. Thanks to US selling wow accounts, we can do this on the first and third puddle phases, meaning you will most likely only need a single dispel for the entire encounter.
Hell, toss in a /cancelaura macro for good measure and you can ensure that you only lose a couple GCDs of potential damage on the boss; I like to use a shift modifier macro so I don't accidentally clear my bubble when I inevitably spam my keybind:
