Does not seem like it would be that hard for them to have all the quests including side quests under each area category and then move them down to finished when completed.
Some of us like to complete an area before moving on.
There are also needs to be a side note "Out of Area" so a quest is not taking us all over the map when we have not finished the quests in the current area yet.
Would much rather have a better quest system than a card game that is not really in flow with the rest of the game.
