What's the point of extra rejoins in SB Live if we can only use 1 per game?

I currently have 40 rejoins, but they're useless for the most part because we can only use one rejoin per game. I understand not allowing more than one rejoin for some games, but if they'd even have 1 game per week where you could rejoin more than once, that would be cool.

I have all these rejoins that are just sitting there going to waste otherwise-I play SB Live 3-4 nights a week most weeks. The only nights I don't play are when I forget or when I'm busy doing something. I'm a hermit without much of a life, so I'm not busy with other things often LOL :) That's the way I like it though.
