Serious concern about rarities

Makerizms

Why is Epic higher rarity than Heroic? An overwhelming amount of people I have talked to about this have agreed with me that it does not make sense to them intuitively and is confusing. In general people tend to think (mostly because of other video games I am guessing) in general that yellow is higher rarity than purple along with the fact that some think that "heroic" just sounds more rare than "epic", I find myself experiencing very often having to correct people thinking Heroic is higher than Epic, I often deal with higher rarities due to what professions I am working towards and I can't get used to it and I saw that with other people that are in a similar situation, and I think this should be thought about seriously. Another lesser concern of mine is that Heroic and Legendary often are thought of as each other because they are both similar in color if you're quickly glancing at them
