i actually didn't notice this, and to my surprise, i didn't get the warrior realm first (was 2 days from getting it).
Anyhow, it does affect the guild realm firsts.
The whole guild had transfered to a new server and we were about to kill al'akir hc. But what had happened just a few days before was that our mage was hacked and the hacked transfered his character away. So contacting a gm led to him transfering back the character (and thus removing the "you have transfered", not really sure why). Anyhow, it meant that when killing al'akir, it looked to everyone else that only he had been present during the kill, which led to alot of whispers asking "omg did u solo??!?+1?!" (same with sinestra btw =p)
oh about fairness, that wouldn't be fair, but restricting me from getting my warrior realm first because i had transfered there almost 2 months before catac release kinda made me sad since i had no special advantage on that new server because of my transfer..
