Save cc and burst for when dragoon buffs himself, forgor the name of it but it's what they get when using geirskogel, but it buffs dragoon damage BUT it also increases their damage taken, so that's when you want to prevent him from using abilities and hit him hard, if it doesn't kill him it'll at least force him to recup spam.

Also if you have LB up, monk LB removes guard if he tries to use guard to buy time.
