agreed, in some situations. But in others it’s quicker to take cover, and stand still when picking up / dispensing packs than to run around trying to make yourself harder to hit. A prime example is for a medic who has just revived someone. If their skill isn’t high enough and their not doing a full revive, it’s easier if behind cover to just drop some backs at the immobile revived player… however, if the medic has any damage he picks them up instead.
I can’t imagine this has been ‘implemented’ to try and make players better players, seems more likely a ‘bug’ to me. However, it also works badly if the player dispensing the packs is near an object. I was in a game yesterday and was in dire need of ammo - i think i was down to 8 pistol rounds only, and no enemy guns to pick up :blah: I found a FO, who was stood just inside a doorway, took a step or two back from him, but although his body was aboit 95% around the structure his players bounding box was not, he nicely dropped 3 ammo packs, all of which were picked up by himself. Again, not something that happened in RTCW.
Maybe i should just be glad you can no longer pickup infinite ammo packs… however you can still pickup guns with ammo in them if you’re full, and it doesn’t take your ammo count any higher, another minor bug that needs addressing. 
Definately! it’s hard enough to get the action icon to popup when trying to swap guns at times, let alone all packs… The priority just needs to be set from pack dispenser, so that they pick up packs secondarily to anyone else.
