Harvesters... your experience?

Here’s my experience:

Recruit harvester not working

All the harvesters have to be reconsidered imo. They are 5* items and almost useless. I used them to fill elemental chests without collecting data, but the amount of whatever should be boosted stayed ridiculously low. Would be much better, if the production was doubled for one day instead of increasing loot from stages, which you won’t play at all without harvesting. I expected 5* items to be much more powerful.
