Never seen a Widow on point get blamed for a loss. Quite the opposite, and I see people telling the other team Widow carried them or Widow on my team gets complimented. Been in games where Widow has even forced character swaps because she needs countered. I have had games in the past where Widow has gotten picks and might be leading elims, but when the team is missing frontline presence and your team is unable to break thru because you have a Widow ineffectively hitting a Rein shield to the people behind him, she isn't contributing as much as people think she is.
As for your second part, what does that even mean? You respond to a post with "no." Do you seriously have no retort to the problem your own posts create? What's the "no" for? Is it reference to your posts where you insinuate DF needs a team around him? Is it reference Rein not always being a good pick when your team is all dive? Was it the Bastion part?
Perfect example of why your posts are confusing and you need to clarify more.

Yes, that's been around for a while now, just not as noticable because people don't really get hit by it often. Had it kill me once because o was low health on Mercy and used SHIFT to fly to someone straight thru a Call Mech that finished me.
