I am an Assassin and obviously not a good tank so am a DPS. I have done many heroics before. Some jerk was giving me a hard time yesterday cause he iconed over the enemies and I attacked the wrong person. As u know ppl like to act tough when they are behind a keyboard. What does cc mean and the icons mean? and What can I do to be more effective in Heroic Missions? Thx for the help

I got kinda off ticked off because it is hard to find groups. The Heroics would turn gray because of my level being too high and only get 5xp. I find it annoying because ppl dont wanna do the missions. Does this annoy you? and Do you guys have any tips to finding groups faster? Thx
