I guess I should explain the pic better. I was using Roma infantry auxillia with the minumum delay set to 50 against unmodded Macedonian Royal Pikemen. Also a charge and attack of 50 give nearly the same results, pikemen were being killed even though they were untouched.

What happened was in the initial charge nearly the whole front line of pikemen fell dead. After that though the auxillia even with there superior stats were routed because they were taking on a phalanx head on. The second auxillia came in and finished the job.

Giving unnatural stats emphasizes the bug, but still show up with plain vanilla RTW units.

Also the test with Urban cohorts shows another bug where you can get a prolonged charge bonus by using testudo to attack
