I can't for the life of me see how this is bad, if you want to play a warzone / flashpoint with friends you go ahead and ask them. Done deal. You rarely add new folks to your friends list, so what on God's green earth is community destroying about letting people like me with less time on their hands get value for the few hours we have available?
It's in no way, shape or form detrimental to your community, but it makes the game playable for people like me.
I could add "are my $15 worth less than yours", but that would bombastic and silly
Edit:
I see replies "No cross server" etc.
What I want to know is why?
What good arguments do you have to support that it "destroys community"?
Just stating that it "destroys community" is not a good (or infact a valid) argument.
