Random is definitely fair, but a few things should be tweaked.

Last night in Keeper, a LVL 1 popped in named Hubbard. He wasn't booted for some reason and tagged along behind. Killed the first mini-boss and the little bastard got a Rift sword... That is absolutely retarded. These noobs should not be able to power-level or get great drops so simply when they don't belong in the first place. They offer NO help.
