Ugh. No glaives. No throwing stars. This isn't Krull, and it's not a Ninja movie. I'd rather keep the "this would be so KEEEEWWWWWWLLL" stuff outta the game. The game, in my opinion, thrives on creating a living, breathing, believable fantasy world. Rare weapons should be RARE. I lke the mix, I find a lot of mundance weapons and so it should be.
The game has a Dark Ages/Medieval European feel with a fantasy twist... keep it that way. I cant stand the katanas... and never use them. The scimitars make sense... and I've only come across one so far, which is good, I just imagine they're imported by the Khajiit, and their rarity makes sense.
That said... I'd like to see crossbows (with realistic load times... no power gamer multi-clips, balance the long load times with an ease of aiming, which is pretty much what their place was in history anyways.) Spears and Pollaxes (halberds and the like...good reach, more or less useless in close), throwing knives.
Natural weapons! Khajiit and Argonian Claws.
Caltrops.Traps. I saw garottes mentioned, yes! (though I would hate to see the game devolve in to a "Manhunt" styled "how can I kill this guy!" game). .
Oh... and my single biggest request. Blowpipes. Poison + darts, plus silence. Awesome.
