I thought to post an idea:
Moonbear was 6KP per other-pet-feeding.
Now it should be ?how-many? KP per NBH-Chest?
Why not make it different and more interesting without being unfair:
It could spend 10min timeboost für every NBH done in time.
This means that a player with 500 provinces wuold have ~250 neighbors and therefore gets 41,6h timeboost out of it. Just a single exploration, not too much.
Anothe player with - lets say 10 provinces, ~5 neighbors would have 50 min + 250min from his fellows.
This idea offers both attractiveness to new players as great flexibility for endgamers. OK, to put 250 timeboosts into exploration is not what it was meant to be but hey: timeboosts are rare, KPs are not.
Feel free to copy the idea where it has to go, if you like it.
EDIT: Let me say, why I had this idea: You can get ~200 KPs from a single pet feeding of the coldfire phoenix. why would you ever consider feeding the moonbear? with that change you would!
