Spectators perspective, would of been cool to maybe have 2 dedicated commentators / casters always talking and keeping it engaging and exciting and other staff would perform the setup/teleports
Post match interviews with the players/gangs would of been a nice addition also. Think more community engagement and excitement surrounding it overall making sure camera was focussed on fights. Dunno if its a possibility but could of given people channel points at the start of stream then each match could have a twitch prediction for the winner and maybe some ingame small rewards for betting on your team.
Ingame title or forum momento for attending / watching the event
Mostly comparing it to a CSGO match in terms of commentating and setup however know that is on a large scale and lot of time to setup but just opens possibilities for next gang-wars.
Touching on Hurricane and Hawky comments;
Announcement post was August 1st with two weeks for the event unsure how long the file was in dev for but perhaps allow longer time to test mission and stream setup.
Like the idea of set maps perhaps some custom made CQC arenas or areas could be made so that it would be new to both teams and maybe release a picture of the layout a few hours before event so teams can study them or allow teams to maybe play on a practice server a week before the event sort of like a CQC or attack n defend server.
