I love Jar Jar! If they made him into a figure, I would definitely get him. Having said that, I would much rather have a SW Rebels Hera figure instead. I wouldn't mind seeing Jar Jar down the line, but I think other characters like Hera, Pamdé, Palpatine, and/or Mace Windu should get a spot first.
I'd also like to say that while I love Jar Jar, I know not everyone does, and I respect that. Hate is a powerful thing however (just ask Master Yoda). While I don't have anything against anyone who doesn't care for Jar Jar, I don't think it's right to be purposefully abusing the character because you are filled with disgust for him. There are much better uses for one's energy than hatred.
So if you don't like Jar Jar, don't want Jar Jar, hope to never see Jar Jar again, that's fine.
But I'm definitely on Team Jar Jar 4.0!
