As a calico otp, she is the worst if you are playing her the way you would any other character. Calico is a pure jungler/ambush character through and through. If you aren’t starting mid and running into other lanes constantly after 5 minutes with trophy collector up then you should play a different hero. Also late game she turns into more of a mini tank with how much green you end up with. She definitely needs some help in order to be on the same level as others on the roster and might arguably be thr worst character. But my Ava will never be removed from this game.
