This change could impact the play style very seriously and is a plain trolling mechanic.
Several enemies on your tail and you know you will be dead anyway? Hop behind a wall ,click drop all and run the other direction.
Got killed in a mass pvp? Log in that enemy team blue suit and "Take All" the shit out of all you can find. Really lame.
This should work only in PVE and in your room, while managing personal loot. In fact, I would suggest to remove the "Take All" feature from all dead player bodies, leaving it only for containers and non-player creatures.
It will make the player looting a riskier task to do and will revive all tactical mini games related to that.
Squads will need to watch their back while looting after a fight because the remnants of the enemy have more time to gather their forces and counter attack. An unorganized squad of loot hungry hobos can take many casualties while swarming the dead bodies, looting that trash one item at a time, and smart players should be able to take advantage of that.
So, just to summarize:
-Add "Drop All" feature for containers in the personal room and bases.
-Remove "Take All" from player bodies.
-After the player body disappears, all his items should be in a container, without the "Take All" feature, so the players can choose what they want to take, but only 1 item at a time.
-The looting process should drain AP. For every looted item.
