Cross server Friend List?

I see the Cross server PF is going well, especially with Anima Farming, Zurvan Ex, and Static forming. Though I would love a cross server friend list if I wanna run with someone outside my server I like, or if one of my friends decided to transfer to another server in the same Data Center. IMO, if they were gonna do something like that, they would need to extend the friend list limit from 200 to maybe 400 and/or maybe make it possible to invite people from other server to Linkshells, though that might be difficult to do.

What do you think? Would you like to be friends with people in other servers?
