Many players were concerned with the Frostscythe's stats because of its inflated +700 stamina instead of plus intellect, which casters obviously prefer, since stamina has been normalized across gear. To be fair, I think it is completely fine to have this holiday fluff item be a non-ideal, cosmetic item that players can wear for it's on-use effect and prestige-luck. Not every item that drops has to be the ideal, especially during a holiday that is coinciding (potentially) with patch 4.2 dropping. That staff you want to be ideal so badly isn't going to be exactly ideal in week if the patch hits June 28. For now, it was an easier alternative to just scale the item opposed to tinkering around and making something perfect. I'd say just leave it as a fun, unique item.
