General Crit Flicker

Hello, I am just coming back after a hiatus. I never got to be too pro but I always loved the flicker build. before this league I got my flicker chars to about 50-55 but then I started struggling because I'd die to fast, especially from desync and lack of damage. I was wondering if anyone had a nice general tree I could use to shape my next one, as either a Scion or Templar. I want high crit based damage and decent survivability. I have no issue with dying, but I would like a fast clear speed. My gear is okay but I also understand things will change as I upgrade my gear. I want a good base to my char as I find in more detail the type of char I want to play. If anyone has a good idea of how my tree should look please let me know. Thanks and sorry for not being more detailed in my question, I'm just getting back today and it's updating I speak.
