sort of less work than keeping a manual / tutorial up to date with changes tho (maybe). I dont really like HoN but I never had to use any external sites/info to learn the game at a deep level, as a you can hover over any value and it shows quite clearly how that is calculated and modified as you change equipment.
while im here another great tooltip would be hovering over the hunger bar and it reading "3 hours 23 minutes until you are full" etc.
