Anybody else think its wrong of how the Argonians and the Khajiit have the same werewolf form as the human races? Shouldn't Argonians be more of a giant reptile instead or the Khajiit look more like Werecats or something of the sort? I know I'm not the only person that thinks they should change it to be like that.

There are such things as Werecrocodiles or something like that in Black Marsh. But no matter what race, if you're bitten by a Werewolf, you will turn into a Werewolf no matter what race. The same for an Imperial if he were to be bitten by a Werecrocodile.

Ah, that is a bit depressing.

Not at all, because their form is being overwritten to that of a wolf (Hence the werewolf). It'd be ridiculous for a reptilian/cat monster to be called a werewolf if there's nothing wolfish about it. If it was a transformation based on what they are like, Nords, Imperials and Bretons would be wereapes and not werewolves.

Besides, as was brought up already, various Lycanthropes that exist in Tamriel include:
Werewolves
Werebears
Weresharks
Werecrocodiles
Werelions
Werevultures
Wereboars

They're found in various regions (the werewolf is found in all of them). If you want werelions/crocodiles, wait till we go to the land of the beast races, though considering we were supposed to find werebears in Skyrim, Bethesda may not include them there either.
