Nah, keep the current method. It would make it too exclusive an activity otherwise. What needs to be done is fudge the tables. You already get level appropriate(ish) items. So what they do, is depending on your place on the overall scoreboard you have a higher, lower, or even nil chance of getting better or worse gear. Now. You can still get nothing either way, but you aren't saying to new people gtfo the crucible, scrub. They'll sit there and think, "-blam!- time to bust some heads. The guy at the top is always getting sweet looking rewards.
