You can use whatever Primary and Secondary weapons you choose as long as the talents are the same.
The objective is to constantly pulse the enemy team and let your team members do the damage....
The overheal from the vigerous chest piece will keep the inventive backpacks talent active for most of the time.
Stay back and let your damage guys do their thing.
Pop the defib heal in the air if someone goes down because it takes much longer to take effect if you shoot the heal on the ground at the downed team member.
Everytime you pick up a downed team member, they will have the BATTLE BUDDY bonus so its time for them to play aggressive after being revived!!!!!!
