There is definitly something wrong. Right now there is simply no reason not to grab a greatsword over another weapon when it comes to efficiency as they just have everything you need without much downsides. Massive range, massive damage, insta stab, high speed, hardly visible at low light levels, retarded feint animations and full damage hiltslash.
In my book 2h "hero" should actually be the hardest class instead of the easiest.
