Agreed regarding the subjective preference for what you want out of the game. However the game has a story, patchy but it's there and the end game content is PvE. PvP exists in a way to strengthen this. Shaxx and Zavala created the crucible as a way for Guardians to hone their skills against the darkness. I can't remember whether it was the Iron Lords or Saladin, Shaxx and Zavala who created the Iron Banner but this was for the best of the best to clash and again become stronger earning the accolades of the Iron Lords. The Trials of Osiris...... alright gonna be honest I actually don't know why the Trials are a thing, but they're to do with Osiris who is another recurring name in the story. The PvP accompanies the PvE story rather than stands apart. But yeah a lot of people can play this game without a care for the PvE and that's fine. I just don't want the devs to forget their priorities.
