Dual Wield?
No matter how much I like about medieval fantasy, dual wielding is just unpractical and lame (for me). I never create a character in D&D/MMOs/RPGs that dual wields, even my thief character in Baldur's Gate, Icewind Dale, and Neverwinter Nights uses buckler and darts.
But then, if it's to wield something purely cosmetic for off-hand (A torch or lamp like in Morrowind/Oblivion), it'll be a great addition to cRPG (Sadly, though suggested a month ago, no news of such implements yet)
