What turned me off the most about last toth is the minimal commentary by the jumpers, and the fact that a lot of times the jumpers didn't really co-operate in answering the broadcasters questions about jumping, nor they tried developing interesting discussions from these questions or anything.
I think this year there should definitely be a lot more commentary about jumping in general, and about the speedrunning community of jumping in particular. Also explaining stuff for the people who never jumped before (which is most of the toth stream viewers) so that they could actually understand what they're seeing and enjoy it would be cool, as well as giving them information about jumping resources like these forums, jump servers like Tempus and notable youtube channels: TF2RJweekly and other channels of different jumpers (also yea, I know they talked about TF2RJweekly and jump.tf last toth but too briefly imo). However, putting these things aside - focusing on explaining specific techniques that are used on the maps being ran while they are being ran on stream is the most important imo: talking about the difficulty (by explaining tiers for example) of the techniques, what it takes in order to perform them, how much time it takes to learn them and get consistent at them; all of these things together will ultimately make it so that the viewers could put what they see into perspective, thus enabling them to appreciate it and to find it interesting and engaging.
But yea, in general - to me it just felt that last toth had too many awkward silences that needed to be filled with helpful and interesting information to the viewers, hopefully this year it could happen.
