As it is, I have virtually nothing left to play for except ridiculous end game objectives (see other forum thread on this). I understand the revenue that purchasing lunchboxes must bring in. And I'm OK with that. But it can't *just* be about buying lunchboxes. Otherwise why play? Give players a reason to send their level 50 dwellers with max stats out to the wasteland! I think the prospect of finding legendary stuff would keep more players playing and therefore increase the chance that some will buy lunchboxes. As it is, there is little point in sending dwellers with good rare gear to the wasteland as you know that you cannot possibly find better gear.
Bethesda, please consider this for an upcoming patch.
