Best way to improve ypur dps is to stop using buffs/debuffs/cc that take your time and help comrades.
"Buffs" are done outside of combat
"Debufs" on enemies are often part of standard combat rotations (e.g. Shatter Shot or Sundering Assault)
"CC" happens right at the start of an encounter. Only rarely is it needed mid combat.
How is your advice of any value at all?
