I have an idea for the PVE events. There should be a “Continuous Play” option. Where when you beat the current team, a pop-up shows on the screen and asks if you would like to immediately continue to the next node, which would keep you on the same board that you are currently on. It could come with a some kind of bonus because you’re not going to the main fight screen to re-up your health. (10% extra points on 2nd continuous, 15% bonus on 3rd continuous, 20% on 4th continuous, etc.)
Some matches are so short lived, so I think this would be exciting to see how many groups of teams you can beat before you die. And if you want to add a gambling effect to it, set it to where if you retreat you lose 50% of points gained and if you lose, you lose all points gained.
I think it would be exciting and fun.
