Greetings! I wanted to suggest the possibility of creating a traitstone tracker. Pretty much checking a box next to a specific traitstone and it would show 0/103 traitstones if you need 103 for your current heroes, but have none. I think this would be a fantastic feature.
The devs have shown no desire to date for this kind of feature in-game, but you never know.
I can only echo what @actreal has said - the site is a brilliant tool, just don’t get too despondent the first time you hit checklist to see how much of everything you need!
