Sarcastic though I am, I actually completely agree with Chao on this one. If it's his honest opinion that Poshul deserves an A, based entirely on character Tilt factor, then that is totally fine.
Thank you. There are 3 categories, and I happen to love Poshul as a whole - her design appeals to me, I have always found her to be useful in combat, and her tongue-in-cheek, non-serious, "comedic relief" personality type speaks to me as well. She's just so quirky and out-of-place in this game, and I love characters like that. Cait Sith (FF7), Quina (FF9), Chiepoo (Suikoden IV)... all favorites of mine.
In my opinion, these types of characters are the best ones. Some people like the "badass", no-nonsense types like Karsh and Sephiroth and such, and that's fine, too. I can't stress enough that we are given more than one poll option for a reason.
On the topic of objectiveness; Even objectiveness is in the eye of the beholder in this situation. After all, who is the mighty being that decides that Poshul deserves a C, objectively? Emotions told me to give her an A, but honestly, I thought she deserved a B. And in the end, that's the grade she got from me. So yes, I was being objective. You can even try and prove me wrong if you wish. Have fun with that, though.
