It?s been a huge struggle for me to level almost everything to level 8 (and all resources building to level 9) and it might take me another year to level the rest to level 9. It?s already hard to do the events and expansion and it would be unjustifiable for any player if level 9 buildings provide little perk except minuscule royal points and money... It just seem to be a craft item black hole.
Maybe we can:
Have a visual different for max level building
Been a pre-request for quests
Drop better stuff instead of just crops
Make it proportional to effort spent bs royal points/money collected
