Advice on Level 60 Retainers, please

[Snugglebutt]

I use 2 characters each with 4 retainers, 4 set to DoW for leathers and 2 fishers for minions and fish, 1 botany and 1 miner. While some are still in process of leveling they will greatly help supply materials I can't be bothered to farm myself despite all my DoL at 60. My retainers are not really for making money, I make the money gathering on my character itself...the retainers are however for helping farm the materials needed to level my crafters while my gatherer character is busy farming items for selling.
