The observe option available for custom arenas and hot join is not enough. Without a post match observe option it is near impossible to review how a structured team performed and where each play could improve… Without this feature some structured teams are requiring all players private steam, this gives them an unfair advantage as they become the only teams able to do a proper review and this requires teams that won’t to take it to that level to have to invest in and depend on third party tools in order to have the same opportunity. It’s wrong and it could be solved if you would build a post match observe mode into the game.
