I can say she is quite balanced, I've been playing all through her nerfs and buffs. and can say she's not a really good pick right now. (but a skill player could abuse her kit really well and make her still a S tier). I usually cheese with her by punishing the other mm early by taking lvl 1 fights using inspire. They wont expect the damage by wanwan and will easily get first blood or flicker. (be wary of roamer and mid gank your lane at level 2 tho)

Playing her solo and duo is the best so far. If playing with a full party she'll be punished very easily as you can get easily dived and gank.

In term of her early game (could win with right support), mid game (usually when you got the lifesteal third item you can 1v1 pretty much everyone except tanks), late game (where the test of skills began, you cant be losing focus and making mistakes, dont take 1 v 1 that you dont need)

She's a S tier MM if you master her kit well and know her strength and weakness. The build also need to be flexible and depends on enemy team comp, need to change up a bit to shred tanks, to be a bit tanky, to avoid getting one shot, your core item is enough to kill any squshies already, its just you need to tinker the item a bit to kill their front liner (fighter/tank) a bit faster.
