Yeah, I think everything about Morag feels sort of badass fron the design to the voice. Also that first fight you have with her ends with that dope cut scene.
If there is one flaw I have Xenoblade 2 besides the mishmash of designs on certain characters, it will be Rex.
Shulk, Shion, FEI or even created character from X that boy is not. The design of his outfit is bad and it never gets better thanks to the chaps. Also he is cliché without ever growing beyond it, all the other characters seem like they have more interesting pasts, if one of the healer rare blades you pick up in the story was not interesting to use and Pyra with her later abilities weren't so deliciously broken, I literally would have stopped using son completely after picking up the fifth party member.
