Destiny isnt a game like CoD or Halo where you can pick it up exclusively for the cooperative or competitive content and vice versa. It ought to be, and perhaps they wanted it to be (and it has improved), but it isnt quite there yet. Bungie designed so many aspects of it to push players to experience both sides.
Therefore, i dont really believe in the "i dont play PvP" mindset anymore than i do if it were said about PvE. It's literally half of the game. I understand that PvE content requires a different set of skills - all you need is trial and error and proper gear to win - whereas PvP is largely dependent on skill. Nevertheless, i cant imagine id ever be satisfied with this game if i chose to ignore half of it. There simply isnt enough in that half. Or rather, you play one half when the other gets boring. Some of my clanmates groan when they see me doing a Raid and im just like "Yo i didnt buy this game to sweat in Skirmish all day".
Ghaleon dont hate me lol. I want the Faction mark conversion as much as anyone.
