Your expertise is above 1300. Given that you start to see a diminishing return on expertise at 1050 there is no reason to have it that high. You can easily swap a Black Hole or Hazmat implant and then augment it for stat achievement. Mindful of asking the question, when reducing your expertise do I have a healer and a tank to guard swap or I am I running pugs? You may need the extra expertise if heals or guard are lacking. Do not be afraid to pull mods from Black Hole gear to achieve some boosts.
