I couldn't agree more - fallout is one man army type of game, balanced for PC to kill loads on NPC, and still stay alive. When we get several one man armies VS other one man armies, "the shit hits the fan", as the game mechanics is not tuned for that type of game.
I am for the pvp mechanics retuning, but I doubt, that Devs will start to do that - its too much work, it would be an almost new game, it would be a lengthy process and no one guarantees success. (as with trading)
