Crowd cam was poor quality.
Some overlays fading in/out (through nodecg control) and some flicking on/off (through OBS) looked inconsistent.
Roaming camera was shown several times while moving (need radios).
Tournament brackets on stream would have been cool.
Intermission music cut abruptly rather than fading.
No polls shown IIRC.
Lighting and background for the casters could have been better.
Casters weren't prepared for replays.
Capture card colours looked weird.
Split screen would be nice, I would suggest showing both teams' medics before pushes.
