Multiple people in a single FC able to place bids for a single FC on a plot

I... doesn't that completely defeat the point of making it so that FCs and individual buyers have 'equal chances'?

No it doesn’t, because people applying for houses on behalf of their FC can’t apply for houses in private wards and vice versa. FCs are only competing with other FCs, and private buyers are only competing with other private buyers.
