Warhammer Online - Crowd Control Spells?

I need some good spells for crowd control in Warhammer Online. I have read once that there is such thing in the game. Is that good or bad? That is the first thing I need to know, because I want to play the game. I saw many videos about the game and I like it very much. I have many questions, but crowd control info is the most important thing for me.

Yes, there is crowd control and many more to the game. It is classic MMO dice roll style game, but it has many fancy attributes like collision detection. Main crowd control spells are used through a stun that freezes player for a certain period. There are many videos that portrait this game “option” and they are easy to find. WAR is fantastic game that is better than many MMO releases. I play it every day, because it just keeps surprising me every time I play it.
