Yes, if the ghetto is insightful, most attackers know they can't rely on t/m support. It's just the reality of the lower tier. I don't like to lump good t/m players into that perception. The other reality is heavy attackers barely ever retal for their t/ms. This is the ghetto way and reflective of their inability to get out of their own way.
If an attacker does retal for the t/m and the enemy counters it usually leads to various arguments about hitting bigger kingdoms etc. Thus, courage and yolo bang heads with fear and selfishness.
