I'd like to point a small fix to
Tage's guide on Horseback:
In the very start, there is the double round block from G1 to first Raiders Leader (camp 20 on guide). The guide suggests that in the block, you'll send generals A and B right after each other. This can (will) however cause your block to fail if you are a fast clicker (happened to me).
What fails is that General B gets intercepted by General A's camp (19) because A won't make to camp in time. I did few rough timings and I observed that the march time from general A to camp 19 is about 20 seconds. I also timed that the moment general B gets intercepted by camp 19 is 23,5 seconds. So if general B leaves within 3,5s (again, a rough estimate) of general A, the block fails.
Solution: Wait for general A to appear outside his camp before sending out general B. At least this did the trick for me, though I'm not guaranteeing on this one.
