I was thinking about it today, and I realized that suicides need to hurt more than they do. Even though it's a beta, I tested it today with the server I play in, and yes, you can continually suicide, then give a teammate your money. I'm not sure what it would take to get this fixed, but I would definitely say that this is not a good thing. Potentially one side could start the game with a negative score, but with 5-10 Atlas Primes.
A possible fix.
Should you suicide, you should start with 3k. Sure, you could still do the same thing, but it's not worth it to do that with the -points being assigned accordingly. As well, it would take a much longer time to get someone a heavy mech. BA's are powerful enough that you could still do damage and help your team.
If anyone else has good suggestions that'd be cool.
