even after watching the first 5 minutes of the review, I can notice something tremendously wrong with what you've said; you say he and his team are incorrect to hold 2nd at top left, they were 3 down (one body being a demo) vs 5 of red to defend 2nd after a lost mid? realistically they should wait for their players (which is what they did, holding top left) or, if possible/necessary, single uber aggressively onto 2nd (time for respawners to come and clean up post-uber). where else would you suggest they hold?
in the majority of cases (such as this one) it isn't _absolutely_ necessary for a higher level player to review the demo (mid is fine) since the mistakes being made are pretty basic and easily pointed out by someone who has a basic idea of how to play. the issue is that, not only will a few things that are said be wrong (such as above), but it's more that a lot of key issues within the player's play will be missed entirely by another lower level player, and probably picked up by a higher level player.
snowblind really just stated the truth for other people to understand, and I think it's fair that the people you review understand who you are, your status within the australian tf2 community (vac banned) and what level you've played at.
