Since starting this character I've been doing what is probably the most basic and common rotation:
Ambush to open
Shadowy Disguise
Surprise Attack or sometimes a heavy attack
then Funnel Health as needed and Assassin's Blade to finish
Character stuff: All attribute points in health, stamina on gear. The Warrior stone. Two heavy, five medium for gear. I go werewolf whenever it's up, but probably won't keep it long term.
I recently replaced Funnel Health with Expert Hunter. Haven't really noticed a difference. Have also been experimenting with Two Handed, but not really satisfied with it compared to Dual Wield.
Anyway, is there a better rotation, or some way I can optimize this one? It seems I'm not killing things as quickly as I should or other people the same level are.
