again only 1 rule applies here.
players should adapt to the rules that are set.
Rules should not be adapted to any players' needs.
If a vast majority of players finds that adaption will (strongly) improve the gameplay, then changing rules might be considered. This is clearly no such case, since most who will want to spend a large amount on a good player know they will have to wait until they have the money available instead of buying on credit.
Do not worry, in a few weks, when you have the money probably an even better player will show up... Buying a star on the TL is not a 1-time opportunity.
They are not your friends; they dispise you. I am the only one you can count on. Trust me.
