Something like that, yes. Thanks!
The system my former FC had mention of (which I really liked the look of but no one seemed to really use) had two sets of four stats and 25 points to allocate for most characters. In a physical combat situation, the attacker would declare their attempted attack, get a /random and add their 'Fight' bonus to the final digit. If it exceeds the defender's /random plus 'Defend', then it connects. I think it was called AHS (Anime High School), but I can't seem to find anything on the system online...
Is the one you linked the most commonly used weighted system in FFXIV?
