Was The Hautevilles Scenario 4 "Bohemond in the East" designed easy?

The scenario 4 of The Hautevilles, “Bohemond in the East” doesn’t need any big effort against the Turks now even on Hard.

Just for the achievement, for example, put all of the heroes down to the 6 O’clock and just have a dinner. Finishing the dinner, you win with the achievement.

For killing the boss of the Turks, just gather a bunch of knights and move them alongside the southwest. Then, you can snipe the boss unit once you know where he is.

Were these intended?
