Suggestion explained in one paragraph: I suggest making it so Helmet and Vest armor values will be orange when they are below 5.
Examples:
Helmet: 3 Vest: 60 // Helmet value is below 5 therefore it needs to be colored.
Helmet: 55 Vest: 0 // Vest value is below 5 therefore it needs to be colored.
Helmet: 5 Vest: 3 // Both values are below 5 therefore it needs to be colored.
Helmet: 80 Vest: 60 // None values are below 5 therefore there won't be any change.
Additional details that are necessary for the suggestion: -
This suggestion is worth the time developing because: It is way more visible and it notifies you when you need a new armor to craft it. This way players can avoid run into the fight unprepared. I guess it won't be very difficult to script it too since it is already applied in food value. I would post it in forum weekly ideas but I can't find any related topic anymore.
