There are some fantastic ideas here! I definitely agree with the delayed damage + stationary; the delay should reset if player moves the totem a certain threshold. Perhaps not giving a free builder on startup would have a slight balancing effect; also, making the builder much more expensive (maybe gold: player.getTribeSize() * 2) would reduce early-game shenanigans. Allowing any class to man a tower would also help- non-archers only do one point of damage instead of the potential three that an archer can do.
