I was not specifically talking about his monks. I was using any class as an example. I also said "moved strategically" so you could not use height. Your knights get in a turn right away; you MIGHT get two of your knights to target him on the first round using CT and the height that they started on, killing 2, 3 max. Then, the person that challenges you has 2-3 units where he can target you by your units' level. If his units were leveled up as wizards, you are dead.
There is no "sooner or later." Your characters could be dead before the first round is over.
