Retchers bots cheats. They immidiately have change due of fire and their granade destroy weapons before hits targets sometimes granades miss you and still destroy your weapons.
I have noticed when using the Squall. When I place one in front of a moving bot , The bot purposely will change direction to avoid the incoming fire storm before it begins.
For instance, in Retchers, most players get frustrated because they think the bots are cheating. They change their direction instantly when you begin to fire at Rizz Lines them, and this makes them hard to hit. There are even situations where the grenade used by the bots can destroy your weapon even before the grenade hits the target. There are other situations where the grenade does not hit you, but your weapon is still destroyed. As a result, most players think that the bots have special advantages that make them superior in the game.
