Scythes are difficult to use...
That should be expected since they're not considered an orthodox weapon, they're mostly used for harvesting crops and other things, the one who invented it probably never intended for it to become a weapon.
Alas, humans can be creative. Sometimes, they'd just make do with what they have. A single moron who used a Scythe to kill some beasts is enough to make it a trend, things can snowball from there.
Ashton was currently in the Simulation Zone, practicing the basics of scythe-wielding. Most of the time, it looked like he was harvesting some invisible crop which makes him look stupid but he did anyway.
That's what the manual told him to do and he's following it. The manual came from the System so it wouldn't lead him astray, he wouldn't suffer a loss if he followed it faithfully.
