Well, in my opinion it also promotes PKing.
Player A has a big weapon, Player B too, but Player B has not enough ammo, so he kills Player A and loot him.
Or: Player A, the big one in PA, kills all who are running around in leather or other smaller armor. And so on...
For me, the biggest problem that Fallout Online has at the moment (in this beta), is the missing roleplay/ the missing people who wants to roleplay. Everytime I played it now the last couple of days, I thought about Ultima Online. IF you have good people, who can make a good roleplay with you, it is really great. But if you only meet people, who wants to kill others and only wants to loot stuff and level up, etc. it is not fun for me, it becomes boring very fast. I mean, this is no WoW or so... the main target for me is to have cool roleplay with cool people in the Fallout world and not only running around, killing stuff and level up as high as possible.
There is a need of gamemasters who can lead other players to nice selfmade quests or so - just like in Ultima Online.
As a good example: For a few days, the thing with the special mission of the unity. This was great.
Bad example: yesterday we were running from south of the worldmap to the north, running around in reno, killing some npcs, back to den, some ugly gopnik (I learned the word yesterday) killed me, looted all my stuff because he wanted to have my armor - by the way, he was carrying a PA and I have had only a combat armor - and so on...
This all wasn't so good because of a lack of good conversation and -> roleplay.
- my opinion.
