Too the extent CC is necassary anymore, yeah, it falls on the tank. Its not 100% necassary but the role a tank accepts is not just to be a meatshield and damage soaker but a leader and field commander. Your tanking style and method as well as confidence directly determines what CC is necassary.
That said, I have tanked so long, my friends often pass me leader to mark targets....when I'm playing my mage or druid :/
Like Vene said, its a good feeling to be trusted by people. Yeah, others kinda have it easy but easy is boring.
your hat may be nice, but I have the little white tank top that says Legendary right across my boobs. I win. (or more correctly, H wins)
