in a group, getting behind an enemy is easy...heck it's easy even without group, but without the short cooldown on stun or whatever it was called again it would be alot harder, you just have to know how to do it right. Don't open up with high-damage stuff tough..unless you can get the creature down to at least below 10% health in which case it doesn't mather and it's better because you won't get as much damage.
