I think we all would appreciate this.
One of the most common struggles that I and many others are shortages of Iso. With new ways to obtain heaps of gold and rank up materials I find it hard to have enough iso for all my champs.
I think a daily quest similar to the catalyst ones would be useful. Currently the game pushes for slower advancement - saving materials for progression - by establishing these daily quests to save up your catalysts to avoid shortages. However, there is not reliable way to obtain gold out side of the first few story acts and duplicating champs. These of which many endgame players have already 100%, and many non-whales do not have the mass crystal openings (no shame to whaling keep supporting this game please). A quick an much appreciated would be to have a tiered daily quest with different types of class Iso. This would allow those with no gold to get more by selling iso, those with a need for iso to get it, and those saving it for a future pull to do so.
