Can characters legally use backgrounds from the Scales of War campaign in Living Forgotten Realms?
The reason I ask is this. In my local RPGA group, every character uses either Born Under a Bad Sign or Auspicious birth to get a significant hit point boost. Character without this background buff are considered handicapped. These backgrounds seem to violate the spirit of the introduction to the SoW backgrounds in Dragon #366:
Each one comes with a small game benefit, usually a small skill modifier. But power-gamers beware! You’ll search in vain for significant advantage. The bonuses are intentionally small because we don’t want a character’s past to overshadow that character’s present. Think of these backgrounds as aids to roleplaying, not the means to eke out an incremental advantage to a skill check.
Also, in the Character Builder, under backgrounds it implies that you may only use Forgotten Realms backgrounds in a FR campaign, and the same with Eberron, SoW, etc.
On the other hand, the LFR character creation guide says that all completed Dragon issues are fair game.
Can someone please clarify? Is any legal character from Character Builder playable in LFR or is this an exploit that should be corrected?
