I think it's rather the developers that missunderstand not the funders.
Kickstarter isn't there to pay for your fancy studio and pay dozens of top - salaries, that's just stupid to think.
It's there to support small groups. When we look at games it's there to support a small group of people who want to make a specific game because they love to make it. It's there to give them a living, pay their rent and food, so they don't have to work to make a living during the development of the game. But it's not there to fund AAA - titles, where you just don't want a publisher behind you nagging about stuff.
Edit:
Now i seem to have been missunderstood here a little.
I don't have anything against bis projects on kickstarter. I backed Star citizen, Planetary annihilation, Project Eternity and a good amount of larger titles myself.
What i rather meant is, while kickstarter should be used to make big projects to, it's main purpose is to make the development of something possible. It's not meant to be like a publisher.
Developers can't fund their projects on kickstarter and still expect to pay a luxurius office with that money, plus top salaries for everyone involved. If they want that, they have to go through a publisher. Now it is of course possible to make really big projects through crowdfunding, like star citizen, but in such a case, you have to make payment possible over a huge amount of time, not for one or two months. And you have to give people the feeling that the game gets better, because they back it. You can see it on the website of star citizen itself that the funding increased significantly, once they started giving stretch goals again. Massive Chalice, for example gave no stretch goals and shortly after it's goal was reached, the amound of pledges dropped significantly. They "only" made around 150 % (169 to be precise), which is a really low amount, considering they reached their goal only a few days after launch.
