Lane pre 6: Get poked non stop by her low cooldown AOE nuke, be forced out of lane or get stunned and killed. Your jungle can't gank her because of easy aoe stun, knockback and slow to let her escape.
Post 6: Get hit by a stray stun once? Even if she has no items, she will press R and kill you with no counterplay.
Teamfights: She gets to freely delete the highest priority enemy champion then barrage your team with AOE nukes and ccs.
Try them!
