I mean id argue that, but your wrong that alot of the FNDM don't find her necessary, but i think she's alot like Ruby and that they'll both have alot of endgame relevance, its just the matter of trying to keep their characters interesting til then, which admittedly they could do better, with that being said if for the next three episodes she fights Winter, Ruby, Jaune and has some closure then sure she could die in the finale, i just feel there's alot of potential for her still thats all. Again thats just in my opinion
