I believe that author of other topic was saying that friends supporting friends influence balance, flow and joy of game more than he would like to.
I think the same as groups of friends on map are worse than multis, 1 high level cheater or wolfpacks joining late in the game.
Why - because friends' packs influence game more than above cases and are allowed.
Simple example - how much you increase your chances to win a game if 10 of you friends donated half of their resources to you = you would have 6 time more resources in the first day than anyone else around. It is wolfpack in a clear sense but hidden behind nice words of friendship.
Same goes later in the game if someone receives 50 times more resources than she / he produces...
Thank you , your Honor. Prosecution has presented it's evidence.
