Not sure if it'll help, but I made this profile for grinding my level 20+ classes, using mend and waste not to cram in as many hasty touch as possible.
You need to be around level 20 and have these cross class skills
careful synthesis
waste not
tricks of the trade
hasty touch
It's not the best, and sometimes I find that I need to tweak the skills when trying to grind new items (like moving from iron ingot to steel ingot). Hope it helps
