Lack of things to do, the school faction is ultimately lacking on RP. Sure we have classes, sports, etc.. is that all there is to school? The entire school displays a lack of good writing, partly due to the students and a shortage of possibilities. Looking at SRP as a whole, the RP is all over. If we remove GangRP, it'll do absolutely nothing besides make people even more bored of the server. I've been in the teacher/professor faction twice, and it doesn't seem like anyone actually roleplays as teenagers. I feel like when I do school roleplay, I'm living a Wattpad fanfic without the drama. "I hate class," "Let's go get drunk!!!", "SPORTS!!!!!". Pretty much all you see. Not only that, many of the teachers RP with students as if they're best friends. Remember, you're that child mentor, not their friend.Move/Copy the customs. I'm sure that's not something that's hard to do. Ranks are already universal across all RpHub servers.
On your last point, I disagree. I try to roleplay exclusively with those not interested in participating in Yakuzas IC'ly. From what I've observed over the past few years is that the Non-GangRPers are the majority. I don't believe my suggestion would reduce the population of SchoolRP to a number so small that it would be inconvenient to play the game.
Unless you can list other "Way more issues" than that, then your point doesn't hold much weight to me.
Hosting another server would ultimately cost more money. The owners would have to hire a brand new staff team, new modelers, and it's a separate server. It isn't a viable option to copy over custom items; that's like copying FantasyRP ranks into SRP. It's more than just clicking a button and boom "new server!!". It takes preparation. They also need builders to build the map, and this suggestion is the easy route. Instead of FIXING gangrp, adding limitations, and making it something enjoyable, we result in kicking them off to a whole new community. Starting a new server could OUTRAGE the SRP community over little things. It isn't an easy project to take on. With an update/expansion list as extensive as the one we currently have in SRP, I doubt any owners would like to work on an entirely new server project.
