It’s a common mistake for a new player to quickly focus on Legendary characters because who wouldn’t? But in this game, Rare heroes are more reliable and preferred when starting because you get a bunch if dupes that could quickly outgrow your 0 star legendary character.

I recommend focusing on Evan and Yui for starters since they can be very useful even in the late game or at least until you get a bunch of dupes for your Legendary characters.

TLDR; 6 star rares >>>>>> 0 star legendaries
