RTF is a global modification that replaces all towns in the game.

The speed should be kept. Hit and return + speed is the main purpose of the creature. Without them, the main idea will be lost.

In principle, the speed can be kept high (let's say 8), then it won't be possible to quickly reach behind the castle walls, and it won't be possible to attack diagonally, and those who really like speed can simply craft an artifact to increase this characteristic.
