Good idea to have mining/botany retainers while working on my first 50?

most likely.

However, just as a tip, you probably want one of the four to be a battle class. There are a lot of things that only battle classes can get (primal weapons, lw skins), and 60 shards/hr extra output isn't worth losing out on those items.

yeah its just to help with levelin crafters then ill go back to 3 -1 xD since i always seem to be extremely low on wind shards n dont get enough time to farm as much as i want
