I'm also rubbish at PvP!!! There really needs to be a way to separate people depending on there skill in the crucible, I'd love to play more PvP but with people more at my level, where it's just done for a bit of fun, and then the better players who take it more seriously can go and have more competitive matches without me having to feel like I just ruined the match for them. I think in Destiny a system like this will be even more important than in say COD or Battlefield, as the more casual gamers will most likely want to play a lot more PvP due to the fact there is loot that can only be obtained by playing in the crucible or events like the Iron Banner
