How about addressing this quote I made above, since it's on topic? There are endless examples of methods in the game to gain a particular resource that are massively more efficient than the many other available methods for getting the same resources. What's the big deal? Why aren't you complaining the amount of Iron you cam get in an in-game hour or two mining is OP compared to looting Iron crap in houses and scrapping it? Mining is far less effort to boot and probably 100x more efficient never mind 10x. Help ma boab! It's OP! Nerf Nerf nerf.
What do you want me to address? That mining iron is the most efficient way to get iron? Ok sure.
If im in a group of 5 people do I all of a sudden get 5x the iron for the same amount of work?
Do I get 13k bonus xp every time I mine Iron?
Do I get dozens of loot chests and containers every time I mine Iron?
Do I get bonus items for mining iron as a reward?
No, didn't think so. Also Mining those i-beams, destroyed stone, blue pallets for cement/cobblestone, etc are all just as good as mining rocks for instance. Looting and scrapping also generates a ton of iron and gives you loot that can be used to get brass, or to gear yourself up so that's another method that's quite profitable as well.
The entire point you keep refusing to address is that the quests are in part OP because its not JUST brass you get. You get
1. Dukes (brass)
2. An entire huge POI filled with loot reset and all the loot in it
3. XP from the quest
4. ADDITIONAL items as a reward when done
And those rewards unlike every other activity are
MULTIPLED by the number of people in your group for #1,3, and 4. Which makes it even more imbalanced when you do it with others.
