Hmm, too much "nya" in her attack though (found one on youtube) :/ Same with the nekomata class in D4... no matter what i tell her to do i always hear an annoying "nya" in the sentence she says while doing it T_T Can't say anything about the other 5 reasons since i haven't played D3 (planning to buy it though).
Fav main char: Flonne. Mainly because of her cuteness, her addiction to love, that she is retarded, her skills and that she's an amazing healer. (at least in D4 where she has the +100% healing evility) x)
Fav class: Mage. Just because of 3 reasons (all related to D4). She doesn't counter-attack, her laugh with the 3rd personality choice is so damn cute and because i like to see the irony when i give her an axe and she destroys everything even though she's supposed to be a weak little girl who relies on magic ^^
