So apparently they have changed things so now you cannot add friends on multiple regions? I know I have friends from before the bnet update who show up on both NA and EU, but digging around the support pages, I found this:
" Added in different Region
Friends can only be added on one region. If you added a friend in US region you won’t be able to add them as a friend again in EU region. In that case the friend will only appear visible in the US friend list. Trying to add the friend again in EU region will result in the error “You’re already friends with Battle.tag#XXXX”
To see your friend in your current region follow these steps:
- Logout the Battle.net App
- Change region to Americas / Europe / Asia / China
- Login each region and check the friends list
- Rightclick friend & Remove Friend
- Send new friend request in the desired region"

In my opinion, this is a terrible change, as it makes how I play and who I play with much more limited, and seems even stranger since friends I had added before the change are fine.
