I played with the tutorial and I think it's a little bit slow. After the narrator tells you what your task is, you have to wait for 5 seconds to unlock the skills/uprades/ units. I think the waiting time should be removed.
I agree, in most RTS tutorials when the narrator tells you what to do you can start doing it even before the narrator finishes talking. At which point the dialogue simply stops and starts the next one, in this case it's the opposite, you have to wait for the entire dialogue to end and then you have to wait a couple of seconds more until you are allowed to do what the narrator asked you to do.
