Main thing to always remember is your not a dps. Also flash is not as good as people think. Make sure your changing targets with rotations if there is aoe dmg. Earlier dungeons drain tp much faster so if your running low faster then you think you should don't worry about that. People will also always give you a hard time attacking targets you aren't.....in that case make sure to keep the hate. In higher dungeons I let them take the hate and get attacked sometimes they learn.
