Just my 2p worth on this...
There are many players out there who actually enjoy failing. Many (although not all by any means) of them are submissive. And even a dominant player will often loose a fight for the sake of a good story.
What I think you will find is that you will probably get a number of applicants for the game, about two thirds of whom will actually start, and half of those will drop out before the first scene change.
This is a sad but undeniable fact of life on Elliquiy. But the half to one third of the players you are left with will usually be the ones who want to play out the story no matter what. You may find that, if you initiate a combat situation, your players may look at the opposition and PM you to ask if you want them to loose.
This is actually a good use for your OOC thread. "Right, guys and gals, you are going to be facing a far superior enemy. Can I have some volunteers to get creamed, please?" Make it open and public, and then if everyone says "No", you can reconsider!
