Actually what I meant is that Grey states in this topic the same thing about Find Weakness that Soirana tests out in his skill guide. It was just a way to convince Andy that Grey was right and Gut was wrong, by providing a third (albeit unwilling) opinion. The GB would contain a YAGBU made by Grey, not by Soirana, so I see no harm in that. IF the skill guide didn't exist, and, for the purposes of the GB, it doesn't, you'd still have a YAGBU made by Grey, initially contested by Gut, but ultimately proven (by others' past experiences, by another's tests) to be correct.
