I suppose... but I haven't played long enough to know. My guess is people wanted to be able to trade them as well? Yeah, this should be updated so people who are new to Promies yet won't go thinkin' he/she can't buy/sell them.
I've killed around 50 wanderers in holla so far, trying to get a damn fear but it won't drop. The other two recollections came very easily, when I was with my NPC getting tactics pearl but this one is being a *****.
*edit:
I've now killed around 150 and have gained 2k exp... this is ridiculous. Is there a reason for this or am I just having horrible luck?
I can also confirm that this appears to be accurate after having spent quite a lot of time farming recollections. Thanks for posting this! It was very helpful. :)
Ill go with the Nixade's post, the frequency of certain animas seems to depend which promivion your in, while waiting for an allaince to show up at promivion dem our party slaughtered a good deal and had all three drop in good quantity, however there where more pain than guilt and more guilt than fear dropping.
Recollections drop off of any mob on any level but it is wisest to farm them from the first level.
All 3 Recollections drop in all 3 Promyvions, but specific ones (can't remember off hand ... I think Holla = Fear, Mea = Guilt and Dem = Pain) are more common in each one.
I was farming recollections with some friends from my LS and we found a Recollection of Fear in Mea (we had already gotten three in Holla, and two Guilts in Mea). Don't remember what it dropped off of, but it was on the first floor.
