I hope this suggestion may improve or enchance the gaming experience.
Once the XP reaches to the highest or cap level, XP sounds like pointless as no other options can save the XP after each fight. The reason is when reaches the highest level as level 155 ( as an example), Team XP will show up “Max Level (for now)” and I cannot save anymore XP unless DS game is upgrading the game. Otherwise, the rest of the fighting and XP will become worthless until the upgrading finish and allows player to get the XP to continue to reach Level 156. I believe some players may put this issue previously and DS needs to address this problem.
Also, if DS game cannot allow player to save XP for future and have an option to sell XP for coins or diamonds?
