It's no secret that the scythe is in a bad spot in the meta and doesn't see much use in combat. Because of this I would suggest that it is made a guaranteed drop from raids again, but its wither skull abilities are removed. This will also introduce a weapon that is better than normal weapons and rares, but does not come close to the power of a traditional legendary. Thinking back to season 3, people weren't afraid to use scythes as they weren't extremely rare but they were also pretty over powered and extremely rampant due to the unlimited silver tokens glitch. In season 4 both of these problems were fixed seeing as the life steal was nerfed, the token glitch was patched and they were no longer a guaranteed drop. Ignoring the legend dupe issue of season 4, the scythe in that state was pretty much unusable. In season 5 after they gave it the wither skull abilities the scythe saw some use, but just wasn't nearly as good in combat as other legends. If the skull abilities are removed and the drop chance is increased significantly, I believe the scythe could become a weapon with decent power and something that people are too scared to use due to its rarity.
