Let’s take a few moments to address this list.
First of all, It sounds like a lot of counters listed like that but most of them were damage and only two damage can be in play at any one time(In roal queue, obviously). Several of the damage Heroes listed are just bad overall so even if they counter DF they are a liability to your team and you are most likely going to win anyway. Or they are map dependent heroes.
The damage heroes listed argument would work better for open Q. Where you can actually have many of them in play simultaneously.
Second of all two of the tanks mentioned are bad overall so if you take them you will probably lose.
Third of all you listed Baptiste. This is either neutral or in favour of DF. He can slam and uppercut him out of the immortality field.His hit box is also very favourable towards DF’s primary fire spread. You might say he can jump out of it and yes he can but DF has the advantage as far as speed of his Combo execution as compared with Baptist, furthermore even if the slam misses him if only Rising uppercut hits him that is sufficient to then finish him off with primary fire.
Bridget is neutral mostly favourable towards DF due to his punch cooldown being lower than Bridget’s bash. Once her shield is broken she is free to farm.
Reinhardt, Sigma, wrecking ball are countered by DF.
Soldier 76 is countered by DF.
Moira is able to use her escape but once she has used that she is a free kill Dependent on the landing the primary fire shots.
