One of the reasons high level players don’t do low-level events, if because the exp, karma, and silver rewards are so negligible. It would be nice if, similar to item drops, event rewards scaled to the level of the player.
It would also be nice for things such as mats (claw, bones, etc..) to also scale, but I could see a few problems with this.
