Addon usage vs skill

I have 6 add-ons,

  • Bartender 4 (Because Spartan UI demands it)
  • DBM (don’t do content that really needs it)
  • Handy Notes (The next addon I like after ICE Hud)
  • ICE Hud (Presents the information I need and that of the enemy around my character)
  • Rare Scanner (Debating do I really need this)
  • Spartan UI (Sorry don’t like WoW or minimalistic UI setup)

3 Of them I like, 2 I might delete, and the last one has to be on if I want to use my UI,
