not to belittle your argument, but....at NT level you have no ideea how many nations just gave up on replicating the tool due to the effort. out of 200 NT +u21 total i would say that maybe noit even 30 used a substitute tool, similar to what you are describing with BBApi.
lastly, this is not a secret game. you have so many datapoints regarding good players and good teams. if some one is truly desperate they would gather better information trying to mine the transferlist (which i know, does not mean alot if the best teams grow their player themselves) or just hack the specific teams account. i am not debating what is best in absolute terms but in limited practical terms as we are playing a free game on a platform that does not allow paytoplay. as a result of limited cashflow i would encourgage the good results...with limited effort.
if i am mistaken and your request is easy to impliment, then i support your ideea, otherwise it s just sharing of opinions.
personally i think the resources of the BB can be used better. apperently the community wanted apps, i still believe doing a merch store with physical memorabilia would allow for better ROI. etc etc.
lastly, i don t engage at all with challanges from users. unless we are friends to decide what we experiment, i just showcase my defence while the other just plays random offense. that is why i stopped playing PL.
