Let me say what will most likely happen if gangrp is somehow removed to put it into perspective:
First off, the emergency factions (KPD and Hospital) will both become practically pointless, cops will not have anything to do at all and will quit 100% - as for the hospital it will become way less active as most situations stem from results of a Gang-Roleplay scenario - then the occasional other events.
Second, the law faction in all would become utterly pointless. As there is no well crime going on it will be left with the choices for only some small cases which could be stupid like loosing an animal or something. They have no reason to host trials and as of the moment (from what I can tell) they are mostly inactive. The only one not affected by this would be reporters (speaking of which good job for the reporters / journalists who post amazing stories!)
Third, the BMD will be completely wiped out. With no Gang-Roleplay the existence of a black-market will become pointless and will just be there for affect. (Unless they switch to something else illegal branching out the ideas, but still no one would be able to majorly use it)
Fourth, Gangroleplay (as we have established) makes up most of if not the majority of the server. Id say barely any of the player-base hasn't atleast done Gangrp once and there is many people who enjoy the idea for the roleplay (not everyone is perm hunger) as brought up, the Yakuza and I have personally interacted with newer and older, well-known and not at all known gangs - this cannot be capped at all a general faction and solely relates on the player-base.
I read a point earlier that stated it should depend on the character, I fully agree with that as do others - if we can find a way to implement this and control the power-roleplay and fail-roleplay plus all other factors, I think it would be a solid solution. But the comes the issue of the player base and toxic players + players who only know one type of gangrp. I think the community just needs to realize it isn't a pvp game but something you should invest lore into.
Anyways, aside from my little rant - basically if you take away Gang-Roleplay, you are taking away the main pillar for the server to run. As stated above almost all the factions, besides the school faction / other roles like animals / adults, will come crashing down. This will stem into most if all of the server dying down extremely quick. Its moreso about finding a solution to the community which is near impossible as you can't control how people act / think.
Anyways! Does this thread include combatrp or gangrp solely? Cause that will also change quite a bit - aside from this, tl;dr removing gangrp will practically kill the server within a month if not less. Okay bye srp have a good day!
