I've been practicing her alot these past two weeks and so many things have clicked with her. Super fun character.
I love hacking individual characters to see how the player reacts to not relying on their powers anymore. The first character I realised went down pretty hard was Genji. As soon as he decides he wants to deflect your bullets, I hack him and finish him off.
Pharah is fun to hack as well, she can still hover but many times she just drops out of the sky and gets eaten.
I could go through each character but it's just really fun learning to sneak up and take away the powers of these characters. I usually try to identify who on the opposite team is kicking the most ass and focus on removing their powers.
Also, learning to juggle her invisibility and transport has been interesting. I can see if they reduced the cooldowns how overpowered it could potentially be. As it is, I've learned to minimize that vulnerability window alot so most of the time I'm harassing from the back causing damage and blinking right out of there as soon as everyone turns their focus on me.
Now that I can play her with a semblance of competency I recognize that most others I run across playing her are...... Less than stellar haha she takes some time
Building your ultimate quickly over and over by hacking health packs your team needs is important as well as denying health packs that keep your enemy in business. Each level requires you understand the layout and pay attention to how your team flows.
