From what I can gather, the timer for the tutorial is actually for technical reasons - LoV seems to be instanced content (it even appears to use the Duty Finder when you enter a match), and because the instance server is timed, the tutorial also has a timer as a result.

But yeah it's frustrating - I was having problems getting the mouse to work (cause by connection troubles and my own lack of experience with RTS games) and thus a simple task proved impossible to do. No doubt I'll get the hang of the controls - it's just the timer only giving you a ridiculously short time to learn the tutorial makes it ridiculously frustrating.
