"Warhammer 40K 10th Edition: Weapon Rules and Army Selection Updates"
The new Toughness stat increase in 10th Edition Warhammer 40K could impact Alpha-Strike armies, which are built to destroy the opponent's ability to fight back effectively in a single round. The increase in Toughness means that armies will be less lethal than before, and vehicles will be able to hold out longer. However, it remains to be seen if this will completely end the Alpha-Strike play style.
