Like last time I'll probably get a lot of biased minuses from class lobbyists for reporting this for some reason, but I never do effective facehug distance stabs against medium+ armored enemies with my DGS anymore due to glancing (it may be that some experience it with the shorter bastard or longsword that has way more room to maneuver) but if you disagree then please demonstrate it in a video or in images, to backup your statements, because I have used great swords for many years and I've always been aware of the problems connected with these weapons (major opponent of lolstabbing and the then current great swords in my TW post history) besides the obvious high tier weapon class of 2handed swords, but though still far from perfect (just like polearm stabs which also has its problems), I've only seen these problems decrease as of the many latest changes in mechanics.
I cba making a vid of it, but if you want i can show you how to make this stabs very easily, you are going to make full-dmg hits everytime with a stab, a lordly armet as helmet would make it more diffucult, but still not rly hard.
2h itself isnt OP, the only problem is that the animations arent working properly, my playstile should not work bcause all i do is making this unrealistic stabs, but this is what makes it so strong atm.
But dont focus on 2h: pikes and spears can do the same, the only difference is that i use 3 directions to feint before i stab while pikers only have their stab.
The stab on all weapons - even one handers - needs to be fixed, since you can do face to face stabs with every sword/spear, and where i hit with the hilt of my sword and a pike hits with its shaft, it still does full pierce dmg.
