if they are the first of their stable to enter Blood Gods they are placed on the last place team for the week as that team needs the extra points the most to stay competitive.
If you think adding a new glad to a group of loosers will add to their points you do not understand your own ranking system very well. What will happen now is that all other better factions will have a new punching ball, who they most certainly will have a 90% w/l against, which in turn will boost their ranking, and the few points the new glad himself will get will be nothing in comparison. If you put that new glad on the winning team, it actually would make sense.
