I agree with the OP here, the Main character needs way more background options than what we are getting now. Needs a background like Neverwinter Nights 1 and 2 if you call them a back ground, where in NWN 1 you are in a hero academy looking for a cure at first. Or NWN2 where you get attacked in a village and sent off or the backgrounds from Baldurs Gate 1 and 2. Or the backgrounds from Icewind Dale 1 and 2, do they have a background its been awhile since I played.
I like the idea and prefer playing a custom character with a background but right now the main character is like a blank slate compared to the Origin Characters.
