Agreed. Personally there should be 0% reaper xp when going below 6 levels (After all, Reaper 10 Butcher's Path isn't as difficult as Reaper 10 LHoX) but rewards should stay intact. Even if players farm out complete twink sets of supreme awesomeness, those include (With full mythic and reaper bonuses, which would likely be a LOT of work) likely around +30 PRR/MRR and +30 MP/RP/SP. While that's a nice little bonus, and strong enough that I could potentially see myself grinding out some items like that, heroic content would not be trivialized by that, even on elite. When you move into attempting heroic content on any skull reaper difficulty there really isn't any huge massive benefit to having these twink sets; there is a decent sized benefit, but nothing game-breaking (And frankly it's much less game-breaking than having +120 HP from tank cores in all content when we're talking low levels).
