The idea was (like many other things) to give players joining later a better chance to close the gaps. So I understand the idea of constantly lowering the sponsors requirements. But the problem is they did it way too eaqrly and most sponsors do it too heavily.
Also at a certain point when everyone starts picking the 20k sponmsirs they will be unreachable for the starters as the requirements have grown vastly while the low sponsors are really easy to reach. This just is the opposite of the planned as this widens the gap a lot.
