Short answer: No.
Long answer: Use defensive cooldowns like Sacred Sheild/insta-Flash of Lights from Selfless Healer, and Flash of Light after you kill a mob to top off. You also have a stun and an interrupt. Like some have already mentioned, Seal of Insight is great for chain pulling mobs.
Honestly even though I'm decently geared right now, I managed to do the Glorious achievement (kill all the Pandaria rare mobs) without any trouble on my own a month ago (barely had raid gear), granted a few of them are lower levels but their abilities still hit hard if you just stand there. Know the ins and outs of your spec, know when to use your non-dps spells efficiently and you'll be fine.
