Imo expeditions are broken because the orbs are too hard to craft vs the rewards.
Boards and faction missions are broken once you max level. Nobody wants to farm board for 2g, and you can erradicate a certain amount of turkeys before you get burnt out of looping these repeatable quests.
What I see is people running elites farm trains in reekwater and other zones for loot.
How can this be fixed?
If board and faction missions gave expedition orb parts and more gold it would make them relevant for everyone, or just remove the tuning orbs entirely.
If expeditions dropped tokens you can redeem to boost or upgrade your gear, it would guarantee a certain reward for running them.
