So, I personally have a large problem with chang'e in...mostly everything. I mainly solo (SWK) and if I meet her in lane the chance of me kiling her without help from jung is basically zero (but that is also due to swk not having high 1v1 gank potential). She can stay in lane from her heal, not back to buy, and have immunity toward any hi burst and the increased movement speed from the dance spread a lot of distance to escape. These issues become even worst in team fights when she is healing herself and teammates with her abilities. And you are unable to body block any of her damaging abilities, and cc-ing to stop an ability is a pretty small window.
So how does one combat a change especially if she builds some cooldown and her abilities are often available at any time.
