With the ability to level up quickly even for high level players, more and more players will be hitting high levels of 700+. With that high level, notes gained from missions and bonuses continue to increase. The 2,147,483,647 hard limit is easily reached forcing a player to spend notes or lose them. Even spending all those notes on skills, we can barely get 600 skills.
Since this is a 32-bit hard limit, I am guessing rewriting all of the code to 64-bit is not an easy task.
Another option I thought of is having a secondary spot to save notes, kind of like a bank. We could then store another 2.1 billion notes in that spot. It would be similar to buying a tab to store extra items in. Thus we could transfer notes from regular-to-bank or withdraw from bank-to-regular area as long as neither area maxes out.
My SPs are waaaayyyyy too expensive now for me to ever win the tournament so maybe not the most satisfactory solution for higher level folks, but I'm cool with it for now.
