You do know i'm talking about the original DOOM engine game, do you? From 1993? Not the 2016 DOOM or Eternal.
I've been in the DOOM modding community for years. Played almost every good megawad that exists. And i never heard anyone modding the game to be about more precise aiming, headshots, etc. Again, it's not what the game is about.
Sure you can play with a mouse if you want and that allows for faster turning left/right and better control and timing. But even then it's not about aiming the enemy between it's eyes to kill it instantly. DOOM never worked this way. The best players don't even enable vertical aiming, for the game to be more authentic. It's about the maps and all the things i mentioned in my previous post, it's not about competition with other players, fragging, headshots, etc.
