After several games, especially against Romans with Seleucids or Alexandrian's armies, something appeared a little strange : trained phalanx have the same manoeuvrability than romans cohorts. Of course they do have to test for oblique movement with march, but with a 9+2 general it is not difficult.
Taking in account that phalanx is a very special formation, my opponent suggest an optional rule that lessen this manoeuvrability.
Maybe it should be as simple as putting a -2 malus for phalanx on any wheel or oblique with a march, and a standard test if they are drilled.
I ask the community : have you the same feeling about this too high manoeuvrability with march ? Solution proposal, is it satisfying ?
