I feel you, I refused to accept any games plot wise after 3 for years, however, with the release of Halo 5, I've decided I will wait until 6 for my final verdict. If 6 can somehow redeem the new trilogy, I will accept 343's games as canon. As for whether we are with the Arbiter or Covenant, we are really neither. This is a place for all Sangheili to set aside their differences, and work together as a species!
