So I got three questions which aren't addressed in the above information:
1. If you've got 3 S-Ranked inner abilities prior to the nerf, will you still have them afterward? I hope so because it'd be a lot of work for nothing otherwise.
2. Does your honor level reset or stay the same?
3. Why pineapple with a good thing Nexon? (rhetorical)
