With three CC slots available at your level, you have too weigh the CC skills. Virus is the most helpful from acn until eye4eye becomes available. Otherwise I found swiftcast and blizz 2 to be the next best to slot. If you don't have swiftcast, surecast can be used, but falls way short. I currently have 1. Virus 2. Swiftcast 3. eye4eye. Even though I just got eye4eye, in the little time I've had it, I am glad I didn't wait until later to acquire it, and I am more comfortable healing having it in my tool kit. Though in these early levels, it is probably not as essential as later in the game.
