I yesterday played on a ctf server that had a increased player respawn time (rbi?) , despite i had the impression that it was not always the same time one had to wait (sometimes announcer starts with 3,2... ; sometimes 7,6,5..), what really was annoying, was the fact that there are no flag status icons displayed during waiting. It is really torturing when sitting there not able to do anything and than not even know what is going on.
I guess it is because one is placed in a kind of spectator mode and ofcourse flag status for normal spectator mode wouldnt make much sense, but maybe it could be changed for players that already joined a team.
