I ve uploaded my special OBs maps.
They are like normal obs maps but have some usefull features:
1. observer in slot 5 can kick other observers during the game by just unallying him (handy vs laggers, bm-observers etc.)
2. players that lift cc in order to obs are automatically after 5 game seconds becoming observers i.e. their units and cc are killed and they get vision and allied to other observers.
3. matchup announcer (even when rdm)
So try it out
