There is not much worse than trying to level up your character to the point of almost going over but not.
It sucks when you happen to do an event that takes you over when you don’t want to because you really have no idea how close to leveling you are. The Logical recourse would be for the game to show you exactly how many experience points you have and how many you need to get to the next level.
It’s not like it’s complicated math or anything, just show us the basic numbers and let us choose what events we are able to do (based off of the XP given) to either level up or stay right below it. Seems like a very simple but extremely useful addition.
