I have a love-hate relationship with the DF.
It's fantastic that it makes it easy to get into content. And because it pulls from a large pool of servers, it helps keep old content alive that you'd never get a full PF group for.
But when you meet some really great people, people that you would like to play with again.... you never get to see them again. Ever.*
To the community reps: Can we get the ability to befriend, /tell, and queue with cross server friends? Guesting would be awesome but really it's those first three that would make a world of difference.
*Yeah ok, technically if you queue the same thing repeatedly, sometimes you'll see people from the last attempt, but after that... that's it.
