I'm actually really excited for a Jaina figure. While there is no doubt in my mind that the late surge of votes was tampering, she was the one figure that seemed to get the most votes in the comments throughout the week. I think there is a lot of legitimate love for that character and I like that she came out on top, even though I'd rather be looking forward to Darth Talon.
That said, I'm beyond frustrated at the tampering in the "Fan voting." There's no point in having a poll where I get a vote or two, if someone else with some hacking ability can account for thousands. Like Dave said, it wouldn't be that hard to put some controls in place to prevent this or even correct it after the fact. The Jaina surge in one day seems almost impossible, and I'm convinced the Starkiller surge the prior two days wasn't legit either. Heck, the initial jump ahead for Talon was probably tampering too if its that easy. I'd rather Hasbro just took the site votes and said, "Jaina got the most site votes, so we're making her." This charade of letting the fans vote just leaves a sour note on the whole thing, no matter who they pick.
