since BC isnt about realism at all but mostly for fun and excersises,
why not be able to save all the dropped lifepacks in an inventory?
so once u walk over a life pack u dont have to necessary use it, especially if your life bar is kinda full allready, so u can like save up allot of dropped life packs and use the life packs only when u need it,
that way u get a much more fun gameplay for BC, it allows u to survive much longer,
thus more immersive experience per each individual player,
so when u collect dropped life packs in bc u should like see this somewhere on your display:
[ + ] x5
and u have to press a key to use it,
perhaps this could be done with ammo clips, but then the devs would make have to make a small box of ammo drop from a killed player,
all the ammo boxes should look the same, but how would u know for what gun the ammo box is for?
well it should give u a stat with simple lining design something like:
that tells u what type of bullets it is, so u know if u are able to pick it or not,
like i suggested in "additional interface"

so u are able to save up ammo's just like life pack's, but this should be used in BC, since BC is a arcadish game mode anyways, a bit unrealistic feature isnt such of a big deal,
and besides, most people that play BC just wanna have fun,
and thats what this idea is all about, increasing the fun.
