when you don't kick some guild of your alliance for don't have any disaray. When you don't abuse game mechnaic for killing the fun
Some of us said a lot of times that thats exactly what was going to happen but everyone was shouting out "hurra! no more alliances! we will finally be able to have our own hide out and cluster in the BZ!"
It is not unfair since every alliance can do the same. Thats the definition of fairness.
