First out i would like to say, i would love to be able to view the twitch chat ingame and for this you have my support!
However i am not interested in streaming implemented into the game as i dont see how it will provide as many options as streaming software do without a significant amount of effort put into developing it. (alas im not a programmer so i might just be throwing guesses here but.. Since there are software developed for streaming i dont see why effort should be put into competing with them or try to substitute them)
This streaming implemented into games or consoles.. It's everywhere and im not against your idea specifically, im just not a fan in general ;(
It already takes some effort to set up a stream properly in terms of audio video and bitrate settings, options for secondary audio and video sources and perhaps overlays.. I think at least these options should be available. If people really want to stream please put enough effort into it, or if you wont, just send people your replays or ask them to spectate.
Sorry if i came off harsh, and i hope it is not against any forum rule. (bringing up my own opinions in someone elses thread)
I might just be a grumpy streamer who won't appreciate the competition ^^
