yep i understand i have one friend here since start of joining, well we don`t actually now each other we just started in same league and i was lucky with them as we never played a friendly, i do have one ( actual ) friend that i invited to play and he`s now doing well.
now on facebook there is un-official T11 group where we help each other with tactics formation and if possible support when we/their playing ( depends if on same server ) and what we can also do is arrange friendlies (home an away) that suit both parties with k/o time.
so from starting with 1 player i know have 20+ friends on my list yet never played a friendly unless it suits.
