Currently, the whole skill rust mechanic is deeply broken, either you can almost immediately lose skills, or you can’t lose skills, just progress to the next level. Personally, I think that both options aren’t what I would like to see, so here’s my suggestion:
IntLevelCap: Skills function as the current “IntCapped” setting, but once your skill level exceeds your intelligence score you start losing levels as well, down to a minimum of level=intelligence, as with the “Int” setting. That way, you can, with effort, become good enough to survive and thrive at a decent level without needing that Enhanced Memory Banks bionic, and you can become superhuman at things if you apply yourself, but you won’t STAY at that ultra-high level for long. The game is obviously balanced around skills hovering at about 8 or 10, so 12 or 14 intelligence will make you nicely skilled, but not able to invariably hack consoles and swat dozens of Hulks with headshots all at once. But, the Enhanced Memory Banks would allow you to progress to superlative heights, which considering its a BIONIC is what it’s SUPPOSED to be!
