I like the mono account suggestion, is a better way to have a more realistic
sandbox game, yes because Fallout games are sandbox, not only pvp shotter games.
Mono account can produce the following changes :
1) more balanced builds, who want to make a power build pvp character have to face with the fact that can't have a crafter, so have to trading with other players that have a crafter to buy good gears, with less pro-pvp builds the combat is more realistic.
2) Factions need more work for join people of different classes, if they want grow strong and have armours/weapons/docs, this fact encourages a relationship between factions that have different classes to exchange everything can be usefull, is ridiculous to have factions with a bunch of pro-pvp characters with alts crafters.
3) less pks and thieves, how many of you have a pk or thief alts? with mono account, only who really want to make this type of game, can playing in this way.
4) More realistic economy system, with trade between people, you need something? ok find a person for craft it or a trader for buy it, is not funny to make all yourself with alts, this is a mmorpg, not a single player game.
I really hope developers evaluate this suggestion, and make it real.
