4 stars: Ok so after playing for over a year, I would like to give 2 suggestions which would help the players very much: First, it would be very helpful if you could provide a skip button for auto cleared stages. It is a waste of time and very boring to look at the screen while farming. Second, please change the limited banner system. It is very painful to see all your saved resources draining and you still not getting the limited operator.
4 stars: Started playing 2 years after global release, the gameplay is both challenging and rewarding. Most stages can be completed without high rarity units thus is very friendly to non-spenders. My only issue is the limited timed events which I cannot do anything about , since I started 2 years late thus blocking me from some of my most wanted characters if not for that would have been a 5 star
