This was by far the most exiting tf2 event for me for quite some time. Mostly due to the great competition and the good old EU vs NA clash tbh, but cups like these are always a good opportunity to have these things besides LANs imo.
From the production side I think everything went pretty smooth as always, so great job on that. Some minor things you might want to consider adding (I'm not entirely sure if those weren't in already since I didn't watch the whole thing and my brain is small) would be stuff like betting on maps with channel points, having replays of key situations during downtime, pauses or between maps or playing some frag movies before or in between matches (Beater does that a lot when producing for tftv). Also the freecam stuff from mitch is pretty interesting imo, it might need some work but could be really good when used in the right situations.
All in all I think it was a great event and production was on point
