Whitemane isn’t played at pro level ever. Medivh is.
Overall the winrate doesnt necessarily mean she is bad, but i would say the evidence points to there being better options for healers than her.
She’s pretty easy to kill and lacks any particularly meaningful cc before 13.
@ others talking about w build:
In my experience W build is a trap that forces an incredibly inflexible playstyle and has a lower impact than her damage build. The issue is that you can’t really take her cleanse without high inquisitor because the downside is very severe unless you have the desperation removal.
It is dumb but having a hero built around doing damage in order to heal have so little damage and have her damage come in the form of a self root and clunky skillshot is arguably worse. The way to get people to play her as they intended is to make that way better and easier than the way people found to play her.
It’s handy to secure kills. And the actual range goes farther than the cast range.
The range once it starts is good but the range you need to be in to get the laser started is pretty small and being rooted that close to the enemy is risky hence using it more as a way to remove desperation stacks
Use it on your allies with the Lvl 1 Clemency.
if you use clemency you’re healing only one ally, its really not something you should use if you can avoid it. You’d get much more out of using your W on an enemy. The main reason clemency is picked is for the W cdr alongside high inquisitor. The active is very mediocre.
I only found Clemecy to become viable post 16 with Shared Punishment other than that it’s not really the best option for healing, well in combat of course, out of combat is pretty ok.
