Smaller coalitions punished, system bug

Shouldn't a 2 or 3 player coalition that wins a map be rewarded more than if 5 players won?

There should be a set payout for 100 man victory so fewer players that have to work harder are not punished. For example, if a 5 player coalition wins a 100-man map, they all currently get 3150 gold for a total 15,750 payout. If only 2 players are in the winning coalition, they should split/divide the 15,750 in half...for a 7,875 gold payout.

How on earth is it fair that the total payout is only 6300 gold because 2 players won and the 3 remaining active (non-coalition) players almost matched that amount?
