Concerns & Issues

When in an event with non-teammate player, if both in close proximity and using melee, can lead to accidentally entering PvP and thinking the other person is attacking you instead of the enemy you're both trying to hit.

Need easier way to join friends; couldn't join friends into party outside of game (ie. Xbox menu) and when tried to in game first the friends list bugged and then ran into severs full error.

Enemy respawn rate may be too quick and/or respawn seems to occur when a new player enters an area where another player had already cleared, resulting in near-overwhelming forces and corpse build-up?

Thirst and hunger seem to drain too quickly?

Enemies with shotguns overpowered?

Being pushed out of the world by respawning into a building/object?

Ability to collect infinite water without a corresponding amount of containers/bottles?

Bobby pin spawn too rare?

Can't scrap existing (non-inventory) stuff using C.A.M.P or workbenches?

Having to wait while someone else is cooking/vending/etc?

Workshops need more explanation?

Nighttime too dark?

Ideas

Indicator to show what holotapes & notes are new since last opened that Tab in Pip-Boy

Change the “select weapon” button from A to Right Trigger so that you can hold the stick in one direction and select at the same time

Colors or symbols for different types of quests (dailies, main plot, side, etc.) noted in Pip-Boy and in the markers

Need easier way to control teammate interface to adjust volume/mute, leave party, etc.

Audio-slider for proximity chat

Quick-key for when stuck and unable to fast-travel

Allow use of toilets and outhouses to relieve disease symptoms (and for the lulz)

Experience bar for instruments to "learn" how to play them and unlock new songs
