The reaction speed should be random (80-200ms or more - maybe quite a tail latency) instead of fixed during training to be more consistent with human behaviour and allow abilities to sometimes work so the bots are more likely to sometimes try abilities when the payoff makes sense...

Dota is balanced around human reaction speeds so it makes sense to have an equivalent reaction distribution, otherwise, it gets arbitrary where a bot trained on 200 ms may behave differently to a 20ms bot.
