I was looking through vids of people going through all the skills of all the characters and I found I really missed being able to easily pinpoint kill skills by their hex shape. In fact, many of the skills are labeled passive and then say kill skill in the description so it is even harder to find. I wish they were better illustrated as kill skills, maybe a skull in a corner or something. The hex is being used for action skills and chevron and diamonds for augments/elements. Maybe if the slanted edge were on the other side of the squares of the skills.
I just want to find the kill skills easily and there is no way to do that at this moment. Maybe future builds will change this? I hope so.
