Unless this is already in the Suggestion subforum, I'm surprised this hasn't been posted yet. Basically, to take advantage of Crusade's massive (and growing) roster, having access to more than one character a match would be pretty fun.
Basically, it's a stock match, but each stock is a different character. So, every time you die, you take control of a different character.
I can already see two problems with it, though:
1. You'd have to load up a bunch of different characters for one match. A nightmare on less powerful PCs.
2. The UI for this might be a problem to set up.
Discuss, etc.
