Not long ago I could count the good ones I’ve seen on one hand but as of the past week or so there’s been a ton in my games, and I’m super confused.
Not yet 
I’ve only seen a few Echo’s & they’re usually shut down by an Ashe or Widow
Not really, pharah’s are more scary after her movement speed buff though
I’ve crossed quite a few lately- but they’re all master / Gm level players when I make note of it.
I have and i absolutely hate this hero. The sticky bombs in particular
Not really. Probably because I’ve been starting to play Echo!
