Pip 1v1s can be one of the oddest fights to come across in the realm. Slows plus using Weightless while facing a wall to give a jump boost should give you an advantage over the enemy. Try to hold off using your heal until you desperately need it.
Flank/Damage pip is not as vulnerable as other builds use more caution when approaching him he has high burst damage and a heal. if your going to flank him try to wait till he shootsthe catalyst on someone else to give your self an edge.
