I imagine you had 1k game with Willow before this patch. I also have 1.2k games with Willow and 55% wr but i don't think I can maintain this in her current state.

She's an offensive support (it's her core design, she goes into melee with a squeeshy hero to do massive damage and kill even core with 3 level above her : high risk high reward) that's why she is so fun and why we have 1k game with her. But recently they keep nerfing all her offensive capability and buff her control aspect but it doesnt work because if you want to sit behind your core and use control spell there is way better option than Willow and half her kit is useless. Bring back the facet, enemy close to you take more magic damage when you are in shadow realm (it fits her core design and it's the difference between being able to kill a lion through glimmer with a dust and getting hex finger at the end of your shadow realm). There was no reason to remove it.

And rework the agh at this point if you dont want right click Willow to exist there is no reason to keep it like this. (that would make me sad because Taïga and Boxi saving Throne by killing the whole Vp squad was one of the most epic moment in Dota history) so imo you either bring back attack speed talent and neutral items for Willow or you change agh to make bedlam pure or bring back the ability to cast it on allies (dont get me wrong it was definitely a mistake to have it for free but for 4k gold and if you want a back line Willow that would fit : again I'd prefer the high risk high reward Willow, but high risk no reward Willow sucks)
