Well if everyone is going to take real physics into consideration on a scythe weapon, I might as well remind everyone of one important detail everyone seems to have missed. 90% of the time in a FF games, you are fighting monsters, not humans.
Yes there are those humanoid monsters and Human fights, but they are few. Now saying that, we already decided that a scythe, while being a poor vs human weapon, can indeed deal massive damage in the right hands. Now lets take a monster, say a Marid from FFXI. Marids are big, slow, and tough. I would much rather hand a Scythe to swing with heavy piercing damage than say a dagger.
Now this works both ways, bees for example seem like a horrible choice for a scythe. I mainly just wanted to point this out, when discussing real physics on a weapon in a fictional game like FFIV, you cant assume your enemy will be human.
Maybe monk's Boost will have a greater effect on two handed weapons, since the update said stat boosts would be improved.
That... is stupid. So much stupid was involved in making that sentence that you could have built a house with all the raw stupid involved.
