It would be really fun to read a list of all the updated units... though some might consider a spoiler. No such lists exists that I'm aware of though. For HoMM there were always these fan made manuals that detailed every last thing, from items to armies to skills.
I wonder if Aurelain is going to update that excellent
Hero Screen for WoTN? I don't know him/her of if they are still active. Is anybody connected?
