Watched the videos. What I would suggest is showing different strategies, and not just a repetition of Tmed with Kavan. For example, try attacking the same NPC once with Brick, and then again using the same strategy with Kavan, which would show people the differences between the two heroes. Most people who search for videos are trying to learn something, like "What is better with level 6 tanks, Dr K or Brick, and with which ability?" Those type of videos tend to be sought out the most.
