Maxing out your retainers changes anything?
In the last weeks, I was spirit bonding a lot and have improved my retainers so they are now almost maxed out in Gathering and Perception (although the ventures only ask for Gathering). They don't use accesoires from 2.3 but have Forager items and overmelded Materia in each single slot available.
Since this, I took them out for 18 hour ventures, quick ventures and also single items, hoping they return either more HQ or more rare items. But so far, zero difference.
SE leaves us completely in the Dark with their mechanics yet again. I got the feeling that adding Perception or more Gathering than needed (highest 18 hour venture needs) does not do anything. Anybody else with well equipped retainers out there who can share their experience?
