As Pathfinder:
- When your team engaging fight, look for option to flank the enemy. A good grapple can bring you behind them before they even notice it.
- When revive your teammate, use zipline back to the place your team die ( provided that the place is clear) it helps them retrieve back their equipment easily
- If your team has Pathfinder, it's a good idea to let him lead the way. Usually, a good pathfinder will bring you to the best spot of the circle.
- It's not necessary to stick closely with your squad, use grapple/zipline to gain gain higher view and spot enemies for them.
