I saw gathering and fishing as part of the mission objectives so at one point people do have the right to gather and can contribute to the mission by doing so.
I think its just a matter of role establishment because without teamwork its just chaos and wasting a lot of time when people don't realize until after they die, that they need to stick together to accomplish XYZ. Especially at the beginning, leaving people behind who have to get their aether currents and are getting killed by mobs who need others to help kill. Its just faster when everyone helps to begin with but that does take cooperation.
ah edit, I saw this post and this is what I mean! Thank you for saying what I couldn't say! <3 /Liked
