Seriously, LEARN TO READ!
I already explained in the posts above how you can complete raid 4 and raid 5 without taking any damage.
And yet you call players, who simply have Valiant Sniper, cheaters.
Are you unable to even read the forum posts in this thread before accusing people of cheating?
The only time when a perfect score gives suspicions about cheating is after the raid tier 6 tomorrow because only in raid tier 6 will it be impossible to beat all enemies without taking damage.
