You don't need CCs, you just need people to not be dumb. Like the pull with the 2 gold droids early in Hammer Station. I was tanking this on my guardian, and just before the pull I see the healer say "I'll CC shield". At which point I lept to shield, hit saber reflect, built up some more AoE threat, and used my AoE taunt when it seemed appropriate along with another defensive CD. Everything died, my health never dropped below 60%, and nothing ever hit either DPS or the healer.
I responded in chat "not necessary ;-)"
Saber reflect is awesome but not all tanks have it. CCs may not always be necessary but they are always a great habit to keep up so people know how to work around them when they are necessary.
