@random Don't use words you don't understand. Unless you believe your overcompensating excess of word salads to be art or "culturally important", don't call people Philistines for not buying into it.
@Swag Wagon Even if I don't necessarily agree with their decision, I believe it was all part of the tonal shift RWBY went through at the end of season 3. This was set up for a while and, considering Monty Oum was still involved, always the planned outcome. Among the many drastic losses that happened in rapid succession this doesn't seem too out of place.
I'm just talking about narrative theming here of course, logically speaking that death leaves much to be desired. An explanation for example.
