In some ways I agree with that dingo said, thought he could probs have phrased it all (a lot) better.
More experienced casters is always perferable, though it seems like it was just an unfortunate circumstance that put gecks and Getawhale on the spot - they did pretty damn well considering they're not top-tier players imo, keeping up a relatively enthusiastic cast despite 'not having any idea about the game' or whatever. Having fragile casting helped a lot cos he brought a lot of top-level analysis in, but he was also the main organiser behind the event (and also played in it) so he was probably busy.
The weird icky green colour was also not the greatest thing to happen but apparently you guys didn't even know for ages so whatever, not really a massive deal to me.
I also didn't particularly like the HUD - not a huge fan of the font because it doesn't look particularly clean and it's too in-the-way, nor the colours used - though I think I'm just really used to the TFTV/VTV huds.
Overall it was still pretty good (especially cos amazing tf2 everywhere; clockwork pls) but as with everything it can always be that little bit better the next time. Props to everyone who worked towards the event.
