Likely Kroma is correct in his assessment of the usefulness of a trusted third party. Yet I have never found myself in any major campaign over the last 3 years in which I could not find at least one player on each side whom I could trust. I'd simply PM them or catch em on MSN and get their take, their word would be good enough for me.
As for hidden conditons, they may be full of peril, but if people control their tempers and realize it is a game they wouldn't be nearly the big deal that they turn into. I remember the "Uber Ships" of RDSL and the stir they caused on a server where an announced condition came into play and how players reacted to that. Many got mad and left, some for good, but a few others sucked it up and continued onward and pulled out the server albeit barely, proud to say I was one of those so I'm not preaching something I didn't practice.
I left GW2 when the server was reset and the rules were changed because as Scippy said I came to play on one server and another took its place. I couldn't have any more fun on it. Why?, because I felt any victory or defeat would have a taint to it as the results would be affected by a midserver change initiated after a result manifested itself. In this case, however, no actual change was made, as Dizzy had planned this from Day 1. Now I can understand frustration from those who didn't realize that such conditions might apply, and if they wish to leave due to finding a different game than the one they had signed up for, it is definately their right to do so, and I won't fault them for it.
However, those who claim discrimination against one side or have conspiracy theories of hidden agendas are totally in the wrong and owe Dizzy an apology for such accusations. I think they are acting disgracefully. I would suggest that if they have such theories they just contact someone on the other side whom they can trust and ask for simple verification rather than go ranting such drivel. And if they don't have someone they can trust on the other side, likely one of their own teammates does. If they and their teammates still can't find a player that is trusted on the other side, I suggest that they quit the game as they shouldn't be playing it with people that they can't give the benefit of the doubt to, and if they haven't built friendships across racial and allied lines, something if likely wrong with them and they should consult a mental health professional.
