Einhar's memory of harvest beasts unbalanced

Hello, I would like to feedback about harvest beasts.
Reason: - Harvest beasts crafting too powerful in many aspects.
- Farming, collecting beasts are very simple, and the party rule is loose to the beast's value. No strat requirement, just need manpower to do by following and collecting (very weird)

Problem: Einhar's memory of harvest beasts will be farmed by some specific group/party. No option for regular players to do it.

Suggest solutions: - Adjust the party's rule to this memory, not only the map's quantity but the map's tier greatly affects member's chance to capture beasts. (nearly 0 at tier 1 map and reach current base value at tier 16 map, lol)
- Additional modifier exclusively for parties: even more resist and life.

Note that I have no information about what's the chance to capture beasts for party members, just feel unable to self-farm and feel very unbalanced overall -> feedback.
