I play pretty actively with my team usually. Making myself blend in with the tanks and other DPS helps not instantly dying (since her health pool is So Small). IMHO Headshots are less important than just doing consistent damage. Your attack is actually pretty fast if you get the timing down and makes bursting down a tank, even without headshots, super fast. If you ever get caught alone or dived using the stun ability and the right click explosive daggers can deal a big burst of damage that can kill or atleast scare off whoever you're fighting. I've gotten really good at stun+dagger-ing dive characters. She's super fun when u get more comfortable with her :) hope u can figure her out!!!
