Hey there, not sure how many people have noticed or were aware that they nerfed the game back in August so that you can no longer acquire legendary armor or weapons exploring the wasteland. This means the only way to acquire such items is to farm lunchboxes (a tedious process) or to pay for them. I'm not sure why it was nerfed other than it may have been related to the time exploit people were using. It's a bit frustrating to spend all this time training up dwellers and getting ready for a bit of wasteland farming (the odds of a legendary were low) only to find you can't even get legendaries anymore.
I'm already maxed out at 999, 999 caps and have more blue gear than I can equip to my dwellers. Please add legendaries back into the wasteland loot tables. If it was because of the exploit it would make more sense to fix the exploit no?
