C sub for LSI is unstable since it elevates Se and Fe and obscures the Ne PoLR which makes them more prone to unexpected explosions. They wouldn’t think of themselves as rigid and rule following but in actuality, they’re the ones more likely to blow up when things don’t go accordingly to protocol. They’re just not adamant or patient enough to teach the protocol unlike LSI-N. It’s an odd case of an IJ with EP temperament.
