How many Retainers

[LineageRazor]

I have five retainers:
Retainer 1 - Wood, cloth, leather, alchemy materials, all NQ.
Retainer 2 - Metal, stone, gems, bones, all NQ.
Retainer 3 - Cooking ingredients and fish, all NQ.
Retainer 4 - Materia, potions and other consumables, a stock of assorted HQ ingredients.
Retainer 5 - Glamour, gardening seeds, fishing tackle, assorted tokens (Goblin dice and cups, favor mats, beast tribe tokens, etc)

Most of these retainers are full or nearly so. I could probably clean them up a bit, toss out some ingreds that I'm likely never to use, but even afterwards I'd likely still need five. They'd just have more elbow room.
