Game mode or new game remodel.
I have been thinking a lot lately about how the leveling system works in game.
Some interesting game modes or maybe even changes to the standard game:
Make the top level come around 12 minutes....or just not have a top level and let people keep leveling up and scale up to 50.
OR
Imagine if you leveled up only to lvl 6 and all your stats were scaled to 1-6 rather than 1-18. Each level would be bigger but you would delay those level 6 power pikes until later.
OR
you start with all abilities and each level up just makes each ability a little stronger. Of course some balancing would be required ....
Would be fun game modes they could put up for a couple months at least.
