Which hero you just can’t stand to have on your team?
For me it’s Medivh. He is simply terrible in below grandmaster games. A good Medivh is as good as an average ‘any other hero’. And an ‘above average’ Medivh is a handicap.
I feel like I’ve lost every game where we had a Medivh on my team. I don’t know why people keep picking him in Diamond…
Junkrat.
Everything he says is annoying. Almost everything he does can mess up your skill shots.
illidan, idk why, but illidan
Sgt Hammer — while a great hero, I still see this one played the worst the most often.
Xul. I have never once gone “oh yeah we definitely needed a xul to fit this team comp”
Nova of course…
Illidan. For some reason they always end up with like 8-10 deaths and hardly any damage.
Oh, yes! Yesterday I had this SL game with friends. I wanted to play Nova, but they really didn’t want me to play her. I picked her regardless and went 10/15/0 
Wonder how the enemy team felt being destroyed by a “meme” hero. They even attempted to counter me with Tassadar (although he didn’t really know how to play against Nova).
But I admit. Very few players are actually good on Nova 
and she has severely limited kit, which makes her extremely niche.
I will be rude.
I am convinced that if you can make such statistics when you play Nova, then you can do the same or better with any other range carry.
Maybe if you chose another hero you would have worse statistics because you would have won the match faster. 
Although i like Xul and don’t mind him in most comps, this made me giggle.
For me personally i think Butcher has to be one of those that are rarely played by anyone who actually knows what they are doing, and when they do they main butcher and play him purely just to play him despite comps.
Thought i have met some insane butchers, just the overall experience with them is not super great.
HYYYYAAAAAAAAAHHHHHH
Not really, I play Valeera pretty well but put me on Alarak and I become a potato. Play what your good at and being good at something doesn’t translate to being good at a similar hero.
Any old specialist hero.
Often played so badly it hurts to see.
Butcher with his suicide charges right after the last death timer…
it’s true also that nova doesn’t really play like a ranged carry. She has a much flankier playstyle a lot of the time than a hero like Valla/Greymane/Gul’dan/Jaina (although Jaina can super flank)
Uther drafted as solo heal (esp on 2 lane maps… ugh…).
Tassadar drafted on any map and in any comp.
Zagara (i refer to her as Losara).
I hate when I end up being right about heroes whose contributions to our style of fighting or map control I can’t figure out. Sometimes I’m wrong and sometimes I’m not
Azmodan. Most azmodan I have had manage to do no real significant siege damage and all finish the game with the same or less hero damage than the tank all while having the highest ammount of deaths in the team. Every time a teammate first picks him Leoric or Malthael incoming and it is a 15 minutte stomp because azmodan is big slow boi and can’t escape.
Nova.
Have had reallly realllllllllllllllllllly bad experiences.
And butcher of course.
But for some reason, the butcher on enemy team always is so calculated and patient in early game… and then you know what a 300+ stack butcher does late game 
Nova
And hammer. Not because hammer is bad, but because most hammer players never unsiege
