I love Warzone but it’s a little bit annoying to face Warden Eternal in every match. Something different would be nice. Who knows… maybe Ripa 'Moramme, The Prophet of Regret, etc. There are plenty of characters in the Halo Universe which could be used here.

IMO, it would be great if they added a special event where Flood Infection Forms appeared suddenly. Dead spartans would become Flood combat forms as well as any dead enemy in the map. Perhaps there could be some Flood growth pods around the map and once they are destroyed the event would end. What do you think?
