(Alternate Fake Warcraft Thesis title: Established Combat Trends and the Declining Incentive for Weaponry-based Innovation.)
When I first heard about the new Legendary, I didn't think too much about the fact that they were daggers, other than for the first time it would be two weapons. I mean, Rogue weapon, daggers. Sure, makes sense.
But then, as more information came out and it was announced that even Combat Rogues (who usually use swords or axes, I think?) would be able to use them without penalty, it got me thinking.
Don't get me wrong, there's something classic about a Rogue dual-wielding knives, and symmetry is aesthetically pleasing to the eye. But at the same time, it's also BORING. "What's that, DarkBladez22? You use two daggers? You and millions of other Rogues out there. Zero points for originality."
Betty White dual-wielding lightsabers? Double swords, how droll.
Think of how cool it would have been if the Legendary was a weapon combination you would normally never see, one that broke the "double weapon" cliche! Like sword/dagger, a pairing just as classic and dating back to traditional fantasy themes of pirates, swashbucklers, duelists, etc.
A hammer/axe combination would be interesting, and could easily be tied in to some exciting new Dwarf lore. Or hell, any fist weapon/non-fist weapon. Just having two different weapons creates an interesting asymmetry and very memorable image / character silhouette.
Even Gandalf didn't dual-wield conventionally!
These pairings would normally never be possible, due to how the Rogue specs favor or lean towards certain weapon types, and always "twin" weapons (as far as I know, anyway.) But since Blizzard is allowing the Legendary daggers to bypass these restrictions anyway, I think they could have broken the "dual same-weapon-type" mold and gotten really creative. There are, after all, so many fascinating and awesome possibilities!
Of course, if we're getting all crazy and innovative, why stop at the traditional weapon classes? We already know the Legendary weapons will be Rogue only...so why do they even have to be one of the already-existing weapon types? Why restrict the choices to daggers, swords, axes, maces or claws? (This argument would be more effective if Rogues couldn't already use like, every weapon ever.)
DUAL-WIELDING LIKE A BOSS
What if Blizzard made the new Legendaries something completely new - a type of weapon never seen before in WoW?
Axel from Kingdom Hearts 2, dual-wielding Chakrams.
This really isn't that weird. Due to the class restriction, Blizzard won't ever have to worry about balance issues, and they've already said that the daggers will be great no matter what weapons your spec is "supposed" to use. So they really had free reign to make the Legendary weapons whatever they wanted. Like...what about whips? A Rogue slashing away with dual glowing, cracking whips would be a sight to see. Or maybe a two-handed, but double-ended weapon like a kusari-gama? (A sickle and a heavy weight connected by a chain.)
A kusari-gama in the movie Ninja Assassin, possibly the best movie name ever.
Alternately, Blizzard could have also simply turned this task over to their creative team and let them come up with some kind of awe-inspiring fantasy creation or combination that screamed badass. Who cares if it never existed before, or if it's unrealistic - this is a world of MAGIC FLYING CITIES AND TIME-TRAVELING DRAGONS. And I think a little exaggeration and silliness, for the sake of Awesome, would be fine. These are LEGENDARIES, after all! They should be pulling out all the stops!
Date Masamune from Sengoku Basara. Yes, you see that right. SIX. FREAKING. SWORDS.
LOOK HERE HE IS AGAIN, FIGHTING SOMEONE DUAL-WIELDING SCYTHES.
These new weapons wouldn't even require new animations or anything - they could just use already-existing animations that match fairly well. And before you say this is a silly or lazy idea, go look at the Warglaives and how they are wielded, and tell me those should be animated like normal swords.
Then again, why would it even have to be a traditional weapon? The Legendaries could easily have been something like the Rogue's bare hands, but engulfed in crackling black flame. Or monk-style wristbands/gloves that, when the Rogue attacked, materialized ghostly dragon spirits that snapped and bit at enemies. OR GAUNTLETS THAT TURNED INTO RIPPLING TENTACLES TO LASH OUT AT FOES oh my god oh my god
I have no context for this screenshot. I think it speaks for itself.
Anyway. My point is - Blizzard had a blank cheque on their hands. No matter what, it would have been Rogue only, and the weapon type was irrelevant. They could have made ANYTHING...and they made...double daggers. :\
