While road of Legend is great and gave the game a new boost i wish for something more like a story unfolds in a book like Heirs of Blood. You can even add a new villain figure (lieutenant) to be introduce in every book. Add more depth to the story and give us a reason to remove the dust from OL cards.
2nd Idea is a Skirmish Kit for more pvp action and get this game into organised play. We have more than 70 heroes from expansions and Hero collections. You can even add lieutenants to the skirmish with their own sheets and abilities (even monsters). A gladiator Arena or an objective map etc (lots of ideas). Lots of heroes sitting in the boxes cause are worthless picking. Give them new abilities or passives that combines with other heroes to create pvp strategies/combos and add a new depth to the game.
I think everyone wants this game to be in Organised Play. Everyone owns it, everybody plays it.
