Bait/10 either OP is a troll or doesn't know how to interpret what he is seeing.
If one watches the top right unit icons, one can see that the SU player gives the command to exit the building at 32:32. It wasnt instant at all.
Oh, for crying out loud, stop with the tunnel vision. This is one example.
The setup/teardown has nothing to do with the problem I'm outlining. Setup/teardown is an ADDITIONAL delay for setup teams.
The game lacks basic garrisoning/ungarrisoning delay, like what Dawn of War II has: squads entering and exiting garrisons one model at a time.
In CoH2, squads TELEPORT, all at once, out of a building or into it. That is ridiculous and nullifies all anti-garrison solutions completely for non-setup teams, while making setup teams require that much less tactical foresight.
