DoL and DoH question

[Johnist]

I built a lancer now but got confused about DoL and DoH that i should take but i know i should main leatherworking
are the mining will work with leatherworking or should i take botanist? how about the shards that leatherworking needed? any DoH that i should take too?

thanks

Leatherworker needs Botanist to support Weaver Craft for the cloths and yarns you will use.
Botanist primarily supports the following Crafts:
Weaver
Culinarian
Carpenter

Miner primarily supports the following crafts:
Alchemist
Blacksmith
Armorer
Goldsmith

Leatherworker is primarily a DoW/DoM support due to needing creature-farmed hides/skins.
