They won't change it before addition now, it will be added in a few days.

Whether they will change it later on will be down to how many actually do the trials, and since some of the people complaining here are more than willing to buy them from mercs I'm guessing quite a lot will actually be doing them.

As I say, I think a lot will end up doing these once they realise it can be seen as a status item and they will join/create shells to obtain them. FFXI has always been about status and it won't take most endgamers long to slip back into that mindset with the devs pushing stuff like this.
