It actually has merits when you put it that way. If teams had access to more builders, they would be less likely to spend their money on "Match Breaker", sorry, "Match Bonus" as their cash would be all tied up.
I would still prefer to see the complete removal of MB and other game play/challenge balances first.
[EDIT] Reason I say "challenge balances" is, it looks like I might have to play CAPITAINE ENFARINE in our newest challenge. I am definitely not ready to take him or most of his Guild on yet lol. It will be an exercise in damage limitation and getting the Gate Money
