Start 15 minutes in. Just one of many games where this happened, and pqumsieh know it's coming.
I absolutely agree that the 3 scout car strat is problematic and deserves another look at it. However it's not the predominant strategy for now, since its effectiveness isn't that well known so far, which was the principal reason for the objection. The scout car on it's own doesn't seem that problematic, it's their number and the fact that Guards are available rather early which counters the hardcounter to the scout car.
Thanks for the replay link. Very interesting.
