Always select Fusillade when targeting a ruckus, it is very easy to land direct shots on him.

Ruckus is an easy target for your ult due to his low mobility

Ruckus is vulnerable when he uses his ult. Remain out of his focus and shoot him down.

Hitting Drogoz shouldn't be hard with your minigun. Your rate of fire is excellent and hitting directly

With the Aerial Assault legendary card, dodging Dragon Punch can be made trivial. Waiting for him to close in to a medium distance then using two charges to jump up and saving one for if he swerves back will save you most times.

During his Dragon Punch, Drogoz is more vulnerable to headshots. Ruckus can use this opportunity to deal more damage, or if possible..eliminate him.
