You make a good point Destram, Once he is invited he will be in tribe for ever I highly doubt that anyone will turn around and say "you haven't improved enough, You've been kicked" The reason I doubt this is that there is people who are extremely in-active now and nothing has happened about that.

I believe if Xguard was invited he would be loyal untill the end and he will become a very good player in a year or so. I don't see the point in this trial. I'd be happy if he was invited but the only concern is that, Is tribe a clan for experienced players or a nursery for learners?
