So im new to the game, please dont flay me for not knowing these things, but i have some questions about DPS. So i just put on Combat Metrics and I saw online that a common DPS was 30K. The problem is that im only pulling 3k and i dont think im pulling my weight as a damage dealer in a group. I know armor, weapons, color (gold/purple/etc), rotations, and criticals can bring your DPS up. I am also aware that my build is not very efficient, I am a magicka nightblade that focuses on self healing (like siphoning), since I did not even know what a build was when i joined.
What i am trying to find out is why there is such a big gap in my DPS and other people's DPS. I am aware my build is not efficient and that hundreds of factors like rotation can make a big difference, but I did not think it would be a 20K difference? I am a little over 200 CP, so it shouldnt be my level that is making my DPS so low.
(please put it into simple terms since I am not familiar with a lot of the terminology and how DPS work)
