I realize that they might already have plans for this but I don't know about them so...
There should be more outside Haven.
There could be other towns with different PvP games or even just challenges and obstacle courses. They could be part of the Krogmo Coliseum only with different challenges. There could be some sort of race through a maze with traps and monsters.
there could be a Tournament Grounds where people pay money to enter and every month the best players get some sort of reward or medal or sword. it could even be held every year and be like Jousts in medieval times.
The paths to the different towns could be like the path to the rescue camp at the beginning of the game. Random monsters could pop up in different places. there could be towns with tier 3 monsters in the path so that tier two and one people can't get through or would need an escort or something. there could even be the chance of rare epic monsters that drop rare epic items kinda like the black kats or something. there could be a maze like jungle with gates hidden inside that bring you to rare epic monsters. They could just be levels like in the clockworks only with more of a puzzle oriented things so that players actually have to think to figure out the way through and if they go wrong they don't get to the next down elevator or don't get the final boss or something. Maybe ranging into the jungle could be regulated by needing a ranger pass or a hunting licence from the spiral HQ that costs CE or CR.
There could also be new prestige missions. maybe one of the locals who is living in the jungle needs a delivery from Haven. or maybe the supply vehicles need to be protected as they go from town to town. or maybe a local farmer has wolvers eating his livestock. or the merchant in town needs some materiels from the jungle.
Or it could be like quests and when you help out the local farmer he gives you something for your troubles.
I'm just sort of spouting out ideas as they come and could go on forever so i'll stop now.
I didnt read the whole post so you might have said this, but where do the minerals go? We could have a minigame for smelting minerals into whatever the skylark needs, which would be rewarded with some crowns, but not too much.
