That's my biggest problem with the Doc too, his crying and raging when he loses is really negative, can't stand to listen to it. It could be a whole act sometimes.
Especially can't stand it when he blames the game and everything when he dies when he rushes an enemy in the open like towards a door and the guy leans out and sprays him down.
He has absolutely no leg to stand upon with his beast of a PC when he blames the game.
That said, when hes not raging, he can be fun to watch. It's amazing how he can kill so easy and his sniper shots are so good to see.
