- Displaying the Max HP value of a dweller somewhere, so we can see what their Max HP is. Reason for this is simple, you've got a load of lv 50 dwellers but some have good hp, some bad and some excellent, all depending on their Endurance stat when they ranked up. Currently there is no way to know which ones to evict to make way for better dwellers, other than resorting to using a save game editor to view the raw HP value. (Not that I have done this, but I understand you can).
- Show which weapon each dweller has on the dweller list, so when you're looking for that legendary weapon you gave someone when the deathclaws came, you don't end up having to spend 30 mins tapping on every dweller in the vault!
- During an incident, if there is no-one in the room when it happens, but one is dragged in - can you not stop the incident if someone has been dragged into the room - wait until they arrive? I've got rooms in a checkerboard layout and sometimes the incident is over before the dweller has reached the room!
- Restore the ability to find Legendary items in the wasteland - perhaps even people. You could restrict this to a end-game scenario, i.e. only when you've got an average dweller rank of 45 or something or only if the dweller survives more than 4 days in the wasteland in Survival (which is difficult!) - basically the only way to get legendaries is from lunchboxes and this simply isn't an enjoyable when the majority of lunchboxes you get don't contain anything useful (500 caps isn't much use when you're maxed at 999,999 caps).
- Sort of related, change the card ratios you get for harder challenges. If I survive 20 deathclaw attacks over the course of a week, I want more than just a stimpack, some basic clothes, a basic weapon and 500 caps! When achieving a challenge like that you should get at least all rare cards or something - something that makes it feel worthwhile!
- Fixing the stacking issue with dwellers when being attacked and ideally stop them moving around, fixed points per dweller slot in the room and get them to stay there during an incident.
- Fix the bug that causes the health bars not to show during incidents, I've lost countless dwellers to this bug, annoying when you've ranked then up to lvl 10 special and haven't had the chance to level them up yet....
Please consider these things as they would make the game even more enjoyable, the end-game situation really does need attention otherwise players simply get bored and stop playing once they've maxed the vault, caps and storage is full of rare items.
Where bugs are concerned, I'm running Android 5 on the Samsung Galaxy S6.
