CC is what? a damage reduction mainly fight less mobs at once take less damage , yes? well as a warrior you can thunderclap to reduce melee speed and most mob dps by 20% you can further demo shout decreasing all physical damage by 10%
so another way of putting it is instead of warriors having no CC warriors CC 28% of most mob damage with the added benefit of allowing AE you might say its lower because of casters but then id point out with pummel charge and intercept there are few if any classes as well suited to make sure the enemy never get a spell off.
so in any mob pack bigger than 3 you have the best CC in the game. you also bring battle/commanding shout, hamstring, pummel, fear breaker, you might even bring blood frenzy.
really if you cant pull your weight with that spread of abilities theres no point blaming the class the problem is between the keyboard and desk
