Gunblade...that is all

[Kiteless]

You're only right about dual wielding, which I have to facepalm anyone that might think that it's not a legitimate combat style. You can find historical precedent for dual wielding pretty much any combination of sword, axe, dagger, hammer/mace, or pick. The only time I'd consider dual wielding as being unrealistic is when you're talking about firearms/crossbows (e.g. Diablo 3's Demon Hunter).

While dual-wielding in melee combat does have precedents in history, a lot of the time, it would rarely be as it was depicted in videogames, where the act of dual-wielding is over-romanticized and overdone in every game to the point of being, at its best, entirely uninteresting.

I could get behind using a smaller offhand weapon as a parrying-blade, but keep the rest out.
