I thought it was just me, but whenever I am surrounded or even face to face with a soldier npc instead of activating my zone attack she will pretty much almost ALWAYs activate her light attack npc killer combo.
There are only a few ways to activate the light attack without a doubt which is sprinting into a zone attack into a mob of npc soldiers which is a huge waste of stamina, or using it at a distance which makes the zone attack less effective.
I have made a similar post on Reddit. With other people who have added to this bug complaint. https://www.reddit.com/r/forhonor/co...n_to_activate/
