I'll answer your questions. I don't like PvP because I'm not competitive. I've never enjoyed making "enemies" out of friends. I find it frustrating because I can't get things like the sword or the Chaperone without playing PvP. Additionally, quest lines that require victories in certain lists force you to rely on your teammates, rather than personal skill. This isn't bad, just bit something I enjoy having to do. The concept that you can earn Nightfall level rewards from crucible bounties and from PvE activity, to me, was a great idea. It allows both PvP and PvE players a chance at similar reward.
