Sounds like people here tend to purify everything under the sun. You don't actually need to do that, unless you've managed to put yourself in a bad position in the first place where you're surrounded by enemies with no allies to back you up. Most CC can be ignored if you're in an adequate position, because you're not getting pummeled with multiple CCs. If you find you are getting targeted, it only takes a few seconds to purify, heal and retreat. Again, unless you stuck your neck out too far.
