What makes everyone think people won't push Electric/Dragon no matter what concept is chosen? Just because Sihk mentioned it in the explanation doesn't mean it's a "done deal", it just means it was mentioned to put the idea out early. Isn't that what all the other people did with their explanations, put things in there just to put ideas in everyone's head? Its no secret that, yes, I would love an Electric/Dragon. But it's kind of insulting to see people think that I would throw away anyone and everyone's opinions just to get what I want.
The problem is that it's a specific type combination mentioned nearly every time, and putting it in the concept, even as just an example, sways the polls already. I believe the poll jumping rule was there just to prevent that.
