With game drifting towards the more 6* and 7* may be soon incomparision to how things were 3-5 years ago. There is genuinely requirement of revamped Daily Quests which will help summoners more with ISOs and Golds.
With 5* R4 and R5 or 6* champs needing more isos to rank up, a minimal quantity of 24 ISOs after duping a champ 4*,5* or 6* barely helps, and even exploring daily quests offers a small quantity of ISOs and fragments.
Also with BGs introduction into game, i would request a few energy refils in the path would be helpful too for the summoners.
This is my point of view to stay updated with how current meta is leading the game.
