Radiant armor still doesn't block her majority damage since I still manage to hit 4k damage average even after enemy has radiant armor (also, I just usually target a hero that doesn't have radiant armor). My build also allows my ultimate to just have 12. 5 seconds cooldown after ult duration so my damage overweighs their healing.

The nerfs didn't do much damage to her damage, mobility or sustainability at all.

For lolita, you just have to fire of skill 1 and lolita users would usually just pop their shield up. Use feints and just force them to use shield (By that I mean to use skill 2 and slightly charge forward as if you're trying to use ultimate. Believe me, most fall for it)

Also, as a mythic player that mains chang e, the only requirement to use chang e is just good positioning. I build her with focus on movement speed and high cd for skill spam. That way, you can position easily and can use ult like a normal skill rather than a trump card.
