Hello, in this I'm going to detail a few ideas that should change borers from their sad state they are now to a mid round antagonist role that actually causes issues while not being too dangerous for the station, all of the changes suggested should be relatively simple.
As they are now, borers and hosts come in few shapes. You either have great roleplay borers that make things fun, or shitters that take you over and make you bash your head in, fill you with fliptonium and generally troll. As for hosts, you either get in security/antagonists who want you for powergaming purposes such as infinite meth, someone who doesn't do anything, thus making you a glorified PAI or someone who will bolt to a vending machine the second you say "hi" to OD on sugar. My suggestions should hopefully make it harder to kill the fun for either side and have them work together as the symbiote the host now is.
First change, remove the ability for borers to take over their hosts, now you may go "Hang on, this is signature, why would you do this?" This has just lead to people hating borers, it doesn't promote any symbiotic activity, it just kicks the player from their own body for a while.
The second change however now gives borer hosts an antagonist flag and objective. "You never knew you were so alone, but now you can hear a beautiful chorus of singing! Everyone should experience this unity! Objective: Protect your borer and ensure the spread to new hosts." This addition will make borers slightly more antagonistic yet beneficial at the same time, hosts will now be encouraged to protect their borer and help spread borers to other people. Now that borers cannot control their hosts, they can reproduce without being in control and they now can also directly infect people next to them with a borer, provided they both stay still, similar to shadowling enthrallment.
The third change, let borers retain their psychic stun ability while in a host, this will give borers and their hosts a tag team approach to things as the borer will stun the victim and the host can cuff them. To prevent abuse and easy fleeing from security, it will take a hefty chunk of stamina from the host and leave them very slow. Meth cannot fix stamina damage.
The fourth change, borers and borer hosts can see other hosts, represented by an icon besides their head like thralls.
With these changes in place, borers should be a somewhat interesting antagonist that will spread like cultists but without the heavy negative effects. Borers will not remove current traitor objectives, only add theirs as a secondary objective. They will not trigger a round ending event but their presence on the station will be taken much more seriously.
Borers are now proper mid round antags.
They can't ruin people's rounds easily and neither can hosts
They shouldn't interrupt the flow of the round too much
They will be taken seriously
Borers can't control hosts, hosts can't purposefully get rid of their borer.
Hosts are encouraged to kidnap and force people to take in a borer.
