Sometimes u can find quite a lot on planet too - Last week found 150 Nissit on TI, 10 minutes later another 115 nissit in the same area. It was my nissit day :yay:
... occasionnaly I found some stones just down the TP
from a slow disciple point of view :
I do like the quest idea. This would make the progession more spicy with some very low value or symbolic reward to disciple or mentor (randomly to only one of them at a time, loot is dynamic...)
I do not think a time limit is a good thing- I play gently...
