Feel free...I haven’t had a chance to look at IZ 3.0 yet. As for Fighting...It’s that way because Parry is based off Fighting, so it was easier to make it always present so people don’t have to select it. If the person has it as unskilled, just leave Fighting as d4 and add -2 in the mod box. If you want to make changes to the way Fighting is presented, I’d recommend getting feedback from the community at large, first, because that’s a frequently used skill, so if it breaks things like Parry or makes it more difficult to find or hides it for existing characters, people will be upset. But I honestly don’t have a lot of time to maintain the sheet as much as I’d like, so feel free to tweak it. :)
