Doing Prot Warrior 3x shaman and 1 holy paladin all with pretty crappy gear and I'm not finding that I need CC at all. My holy pally just spams the crap out of FOL on my warrior and the shaman's drop crap so fast that my warrior doesn't take a ton of dmg. The only time I've actually had to worry about healing to date is when I get to the boss, which with 3 back up healers isn't really a problem.
