How to change serve, to connect matches of friend and can transfer?

[tungnguyenart]

I knew i can't connect matches of friend and can't transfer with them because me and them are diffrent servers. But... I have 5 friends, just only one connected entire with me, 4 remaining can only play friendlies, I felt worthless! So how can we change server to connected entire! May be this was not bugs but i think every one play Top 11 look this is ****ing big bugs.
