When you put your mouse over the unavaiable option, you see the reason why you cannot choose it. In this case its the white that wends. The +1perception is irritating in this moment. While it is importent to know that this background gives this stat bonus during character creation, the information is completely useless later because you cannot change it anyway.

 

suggestion:

The stat bonus you gain by selecting a background should only be shown during character creation. It should not be shown in tooltips during normal gameplay.

update:

This is true for all tooltips in conversations, such as background, race and so on.

Seeing stat, skill and talent bonusses will not give you any advantage during a conversation. You have the stats, skills and talents that you have and thats it.

There should be a difference between lore and game mechanics.
