I can say the damage from Skill 1 and Ultimate is very high if combine with the right item, it seems quite overpowered than other mage, as exchange of that high damage, Chang'e skill 1 have low area and the Ultimate is straight, the movement speed from skill 2 is for her survival, i think Chang'e need slightly nerf on her base HP and DEF and reduces the damage of skill 1 or just remove slow effect from skill 1.
lol. yes her most annoying for me is her slow from skill 1. its ridicilous.
as i remember dev buff her slow and damage from skill 1 right before they sale her lucky box skin.
She's not that OP, it's just that she is a hero that can use magic item's passive stupidly effectively.
That Burning Item and Ice Queen Wand slow can be triggered by Basic Attack with the use of 2nd Skill and Ult. SPAM SPAM SPAM Just like Kimmy but better because she doesn't need energy.
