As a caveat, it is possible those designers are relatively capable C# scripters that can handle much of the client side work, but their bios read more to me like traditional design. At the veryleast, making an MMO with Unity, you'd need 2 engineers. One client and one server.
I know this doesn't matter to most of the people here, but I thought I'd say it anyway. I am not going to go all crazy spouting hate, because it is pointless and not who I am. I would just rather see Kickstarter money go to young developers that are hungry to create the next big thing. Yea, it is a risk, but at least there is a chance, and new blood in the industry is something sorely needed.
