Struggling to apply aim training to games?
Try thinking about how the game is different from the scenario, and change that.
Bots much bigger than heads, try to go closer to head size.
Be careful, as if you make it too difficult, you'll overwhelm yourself. But it is far more common for people to go too easy than too hard.
This is not to say easier scenarios to work on certain techniques are useless, but rather to say that if you only play scens where the bot is 4x an enemy's head size, you should try a scenario where a slower bot is the same size as their head.
