Disco fever too hard for disco chomper compared to other legendaries

Disco chomper legendary meter 'disco fever' only registers for eating the enemy. Not for other kills like biting zombies in the face or goop kills. He is completely vulnerable after eating/swallowing as we all know, and it proves super difficult to get to disco fever in a real multiplayer match, unless you are just going to try to pick off random strays and be away from the action. If you are actually going to be participate with your team and be part of the action, you won't make it to disco fever. His meter should move up with any vanquish (eating or biting) like the other legendaries. Exception of toxic brainz noted since his meter only moves by punching. But even for him, each punch that does damage moves the meter. It's not based on vanquishes at all, just punch damage.

For disco chomp, please change his legend meter to move on all vanquishes.
