I am leveling a Nightblade and I have to say I love it in fights with 1-3 opponents. What makes me cringe, is when I see more than 3 enemies in front of me. Like public dungeons.
I usually open with Volley and then useTwisting path and Whirlwind skills in such situations, but it's just not enough. Whirlwind becomes really useful when my opponents are low on health, but Twisting path's damage accumulates very slowly. Or, at least, not fast enough for my cat.
So ... how do use your NB is such situation? Which skills and/or weapons do you find most useful against large groups of enemies? Which ones are good for doing AOE damage or CC and which are good for survivability?
