Don't know how it happened, but I had a 2.3 LS sword with holy damage that had the holy graphics. It was a Conquest Sword.
Let me know if you find one with lightning graphic! :-D
I wholeheartedly share your vanity views on weapon choices. My Monk has never worn a sword, because it simply doesn't look right. Daggers are cool, but I still prefer the look of a fist weapon (Heaven Hand and the likes of it being the best there is).
That being said, unfortunately you won't be able to get a hold of a LoH/LS weapon that doesn't display the red drippy effect. Sadly, those two affixes override all elemental effects on a weapon to the extent that even if it doesn't have built-in sustain, but you choose to socket an Amethyst into it, the red drip will kick in and obliterate whatever elemental outlook the weapon in question was sporting prior to the socketing.
The only way around that, I guess, is if you resort your LS to a Legendary fist of your choice, as these have fixed appearance, regardless of affix rolls. WKL looks awesome and totally complements another lightning-based weapon as it emanates a pale-golden sheen, reminiscent to the electrical surges that lightning weapons produce. Can't speak for the Fist of Az-Turrasq or the Crystal Fist, as I've never seen them equipped, but the Shenlong set is to be avoided like the plague, for the sake of any semblance of aesthetics. And who knows - maybe the new Inferno-grade lower level Legendaries will bring us a whole new array with good-lookers.
Yea, female monks poses aren't that good for swords. Plus we punch anyways with FoT at least. I'll probably transmog WKL when that feature comes available, but still like the normal rare lightning effect a bit more than the WKL one. "Useable" WKLs are way too pricey for me though. My current weapons cost 200k so I'd have to add a few zeros to afford a low dps LS/socket/% one.
I have a few fists saved up for the eventual transmoging set, and made a few pics for reference. Not too shabby, and I'm sure their model will be used if not actually used if they get ilvl 63ed.
