I would agree with you on this one.

Things have improved somewhat since players complained about the leagues and targets set, and there were some changes,however these changes may not have been fair at the outset and may soon be come outdated and subsequently even more problematic if they set high minimum targets ,like they did, and to a certain extent still do  in the quests where unobtainable  items are included.

It seems you are in a clan after all and it seems it a clan competition where from personal experience I can tell you that  its almost impossible to get the first target in many cases,especially if the clan members are not taking part,and effectively impossible if its a one man clan.

My assumption is based on limited data but it would seem that the lowest targets in a league are a fixed amount no matter the size of the clan which is why its so unfair on smaller clans to be expected to hit the same totals as those much bigger in number( and up to the maximum which is unknown to me)
