What are the usual heroes you pick there and is there anything you seem to have issue with that you know of?
Usually Lucio for KotH but sometimes, if needed, I will play Reaper or Pharah on Nepal because both of them can do some work in the right situation.
during/after play what do you observe was the problem? A particular enemy kept killing you/teammates? Better enemy coordination? Ws your team lacking in survivability/kills?
Well, last night, no one wanted to tank. So I picked Zarya but once we got towards the point the team just split in all directions. Like everyone wanted to be the flanker, no one went for the point. A few more respawns go by and someone finally picks D.Va so I switched to Winston since I couldn't get anyone to group up with me. We lost the round but that went marginally better.
By round 2 the fighting started and one guy was calling out our Mcree by saying he was trash and couldn't hit anything (I don't know, I wasn't watching him) so as a troll pick the dude changed to Symmetra.
It was pretty much down hill from there.
I'm not sure why that particular map seems to be more problematic but I've had teammates that trickle in, never group up, seem to be playing TDM, don't communicate, you name it. All of this stuff happens on other maps also but for some reason it is Nepal where it all seems to culminate and produce the worst blow-outs.
Now I can't control randoms but I can control what I do and I am always looking for ways to improve.
