I feel like the limit system is one of the biggest reasons to get a rank, and it brings the server money therefore. Of course this might sound greedy, but the server does need money to run and pay employees. When I was stone rank, I had no problem keeping all my important friends in my 10 slots. It actually was enjoyable because I didn't have a ton of people I didn't play with or hardly know (like I do now.. yikes). Also, if you really needed more than 10 friends, you can always add them on discord and just not on the server. I know someone who is a rank and has 0 friends on their /f list. Idk, it's just a perspective thing but I doubt the limits will be changing.
