Can we combine daily scrolls on xbox and is there a expected date for family name in chat ?

No.

I don't think they're good ideas anyway because if you stacked 12 Moghulis into the same instance, it would get ridiculous. Fun though, I wouldn't mind trying it for giggles, but it'd lag the console a bit, I think. 

As for the family name in chat, it would potentially take up too much room in an already crowded HUD. What I would like is to somehow rearrange the HUD to personal preferences; resizing hotkey and health bars, removing chat and quest HUD sections (but be able to quickly switch on again for certain quest circumstances), maybe even make quest section show only 1 current quest instead of 5(?). I'd also like to be able to switch off the whole damn thing to appreciate the horse riding and terrain aesthetics and have just the hotkey and health bars reappear if attacked, then go away when weapons are put away again.

Family name in chat could be like a selectable setting. So you could choose for chat to display family name instead of character name. Might complicate inviting to party from chat, though. But it's an idea! ^.^
