Disco fever too hard for disco chomper compared to other legendaries

To be honest here, 90% of the time I'm using a party character in a Multiplayer game, I never make it to the party boost because of the high kill streak required. The overall party characters' nerf only make things worse. Surely online players won't make the chomping any easy, and the character often dies before filling the disco meter. The overall reward for being legendary and to be actually worth getting is rather questionable by the poor performance.
