it`s always a bad ideea to combo nerfs ,rather than wait to settle down

and i am talking about ,

1. he received more Q healing and more mana regen a patch before lethality went from 40 to 60%
2. this patch you nerfed his assassin masteries ,which add % dmg to low hp targets (finisher) and bounty hunter and precision(lethality)
3. you nerfed youmou ,his nr 1 item ,then you nerf/hotfix edge ,thats 2/3 of core items
4. you nerfed his passive on PBE , his Q early dmg by atleast 20 (you max Q rather mid game) ,his W also nerfed CD

wait this to settle down , dont let things geshiton by chain nerfs.

this is my ideea of why balance team sucks sometimes

they do not stop after indirect nerfs to items/masteries, the wanna messs with champion too like cinderhulk and . never learn.
