Just want to add in that both Scythe and practically all Pole Arms can be used the same as a Bo Staff adding in a different style for fighting. While the argument itself is pretty worthless as it was also stated that this is a fantasy game where real world physics and use don't have a lot of say on what can and cannot be done...I mean look at the Magitek Armor and the Highwind, neither of those would work in the real world.

While the Scythe is inadequate with use, it can be used in a fight. A Killing blow is just much harder as you have to be in a favorable position to be able to pull the scythe into the opponent while they are ensnared within the cutting edge. Sickles are used in a very similar manner when you have to use them to fight with. Practicality wise, yes, they are both cumbersome and nearly impossible to use, but that doesn't mean they cannot be used.

That being said, I don't see it getting much use outside of a DPS weapon, while I'd like to see it on a DRK, I can't if its based off the GLD. DRK would require a new class in order to use the Scythe and I think it would be better fitted to a more sinister dark art such as Necromancy...IF they don't give Necromancer to the Arcanist cause a common weapon for a Necromancer is a Grimoire and their playstyle would already match the general set up of an Arcanist. Possibly a DPS class with more focus to Debuffing and pet manipulation than the SMN with unholy healing abilities.
