Increasing club size

I would like to talk about the clan. Right now there is a limit of having 50 people in a single clan. But what if there are more than 50 people who has to join the clan? As a solution, my clan master made a chat room for the clan. But, he was wondering why there weren't many people joining and I found this today after I updated my client. There isn't a setting like that! Getting back to the point, There should be in increase of how many people can be in a single clan. Riot shouldn't be limiting the growth of the clan rather they should be supporting the growth of the clan.
