I'm pretty sure this would be a pretty easy update to do, and i am sure most if not all the players would be thrilled to have a treasure counter next to each treasure that would show their total pulls. Seeing how the game has a fixed number of rare drops for each 60 pulls a rare or 200 for super rares in some treasures (well the numbers change depending which treasure we talking about). i am pretty sure each treasure already has a counter, you'd just need to make it visible. i thought about this and i don't think there could be any bad drawback to such an update.
