I won't say that their buffs to Scythe were as big as their buffs to Great Sword, but they didn't forget Scythe:

They more than doubled the fTP of these weaponskills at 300 TP. Insurgency is particularly striking, as its combined base damage multiplier (including extra hits and assuming ~20% DA) goes like this:
3.9 -> 6.65 -> 9.4
Considering WS delay and the nearly-linear scaling, Insurgency users might as well sit on TP essentially until they are at 300 TP (or at least until someone uses a WS they can skillchain off of). It is a very unique playstyle right now.
