also, as far as the CC problem is concerned, look at that sectioned blue bar under your health bar, above your head. 4 blue bars means you CANNOT BE CC'd until they wear off, which takes 15 seconds IIRC. So, if you get repeatedly CC'd, you'll temporarily become immune to them. Which makes it smart, to, ya know, not cc people with a full blue bar. The cc would be wasted. The CC bar also counts things like those ****** little 2.5 second 30% speed slows as 1/4 CC bar.
Honestly, PvP just takes getting used to.
Edit: typos.
