Warding isn’t a gem stat nor is it for OoC because it serves as the only permanent stat to counter insanity, which is its negative stat.
Agility should’ve been made an OoC jewel stat from the start because it has no real counter and quite niche, same reason why swimming speed became an OoC mechanic. All of the armor stats have a counter except agility, which requires you to run the same stat just to get even, highlighting the word “even” when it comes to fighting against agility.
