It may seem retarded to you, but I still think its a valid point. The only way to prove otherwise, or prove that I'm right, would be to test the system. I don't really like that idea as a standalone option, but that's not what the consensus is right now. If its used in tandem with a segmented passive regen, then it could work, but while legions flourishes on PUGs and clan games, the game also needs to work on PUBs. One thing we have to keep in mind is that this game should be able to appeal to new players. In case you don't remember, there's a steep learning curve to this game, learning how to cope with the greater movement and trying to hit small, fast targets. For the first while, its hard to get frags. New players could finally get a kill, and then need the health drop, only to have it picked up by somebody else, or they could start taking other health drops, and frustrating the more experienced players with their 'noob-ish' ways. If we want this game to get popular, it should be more accessible to newer players.
This is why I like the idea of getting a certain percentage healed from visiting an ammo reload station. There could be a time limit in place so that if you get a health pack, you have to wait for a certain amount of time before you would get another health regen. This method doesn't put too much of an advantage over either defense or offense since they have the same resources. If there was some way to make the time limit longer if you collected a health regen in the enemy base, it would put a bit of a hindrance on the LO. However, whitewhale's complaints about the LO are just complaints about the LO doing what they are supposed to do.
As another idea for a compromise, there could be segmented passive health regen, health drops and regens available at reload stations, but health drops heal more than the ammo stations.
Also, above with my remarks about enemies being hard to kill as a new player, Legions was the first shooter game I played on PC, so its possible that my experience differed greatly from other's beginning experiences.
