First off, keep the topic and discussion relevant to the title of the topic - the observer mode. There are plenty of other threads where you can kindly discuss on the number of bugs or balance issues prevalent in team games and whatnot. This is not the place to bash Relic for unrelated things.
Second, observer mode has been one of the most requested features for CoH2 for a very long time. It's something that's been sorely lacking for a RTS that "aspires" to be eSports. There is no denying that Relic received a lot of flak for shipping CoH2 for what amounts to be the same, feature-wise, as CoH1, but dressed up pretty. The current replay and cast system is so laughably archaic and cumbersome. Live spectatorship is critical in generating hype and excitement, and in this day and age of Dota2, SC2, and LoL, pretty much required for sponsors to chip in. Live obs mode has been requested time and time again, and this time Relic delivered on it. The fact that Relic has released this for the general public means they are in the very last stages of the build and is almost ready for release, with some bugsquashing and polishing left to go. This is very good news, and one of the best streams Relic has done - for its subject matter, at least. We should be cautiously optimistic heading forward, and it presents opportunities for future tournaments and the ESL for more viewership.
Third, although the interface is quite clunky and functionality does not seem to be very elegant, it is at least basically functional. I will disagree with the design decisions (as with lots of GUI issues within CoH2), but at least all the important bits are there. Hopefully, sometime in the future within their 5-year plan they will optimize and streamline the interface so that it will look as pretty as SC2. Relic employees, take note:
Currently it is way too cluttered, too busy. It's also lacking shared FoW, multiple players' units. Maybe other goody stats with a push of a button - APM, sector counts, and so on. For the overlays, god forbid that it'll be used for 4v4s! There's still too much blank space, or just unnecessary detail which aren't really needed.
Everyone should at least be happy that Relic finally delivered something somewhat closely resembling what they wanted. Just give it time, it'll be soon™.
