How am I supposed to be playing Blade because I don't get it.
Am I supposed to E -> Shift into tanks? I seem to melt instantly.
Am I supposed to chase DPSes? Because it seems like if they're not alone I just instantly die.
Am I supposed to go around and kill supports? Because no matter what I do I can't seem to outheal their damage output or healing, and basically anyone can CC me.

I've played like two or three hours of him now and I have zero understanding what I'm supposed to actually do to make him successful. When do I leave an encounter? It feels like life steal either is so broken I survive everything or I die from a stiff breeze with no in between and there's no difference between attacking the squishiest healers ever or Groot.
