Ruby might still take the cake for me, with me honestly like her cheerful optimism (though she never seemed too naive, like other characters of the type seem).
Qrowe would be a close second, just because he's that awesome and can easily steal whatever scene he's in.
Well, Weiss has been Number 1 for me since forever, and I don't see that changing anytime soon.
Second is Qrow, cuz he owns every scene he's in, even when he's not in them (the scene where Taiyang talks about tricking him into wearing a skirt. We were all thinking about Qrow in a skirt)
So I said Blake is my favorite character. And she is. But I realize now that I wasn't being true to myself. My #1 fav character is truly Weiss followed right by the rest of Team RWBY as all tied for #2.
