Obviously implementing all the "breeds" of Khajiit would be a bit too much, but a choice between, say, Ohmes, Ohmes-Raht, Suthay-Raht, and Cathay would be excellent. With each "breed" having different stat and skill modifiers. For example:
Ohmes: Less strength and agility, but greater personality, and maybe receives no prejudice from other races due to their human appearance. (Maybe some tattoo options?)
Ohmes-raht: Medium strength and agility, this "breed" would act as the middle ground.
Suthay-raht: Same as in Oblivion.
Cathay: More of a brawler, strength oriented Khajiit, less agility, not as sneaky, but with much higher endurance/strength.
(And, for those that don't know about the Lunar Lattice; Depending on the alignment, whether or not they are waxing or waning, etcetera, of the two moons, a Khajiit will be born with a different "form". Ohmes look pretty much like Bosmer, but tattoo their faces to look more like their relatives. Ohmes-raht are sort of half Suthay-raht[the type of Khajiit in Oblivion], and half Ohmes. And Cathay are like Suthay-raht, but much larger and stronger.)
And seeing Ta'agra as an actual developed language would be excellent as well.
Anyway, anyone agree, or have anything to add on the subject of Khajiit in TESV? In any case, thanks for reading!
