Orcs vs. Humans

I already sent the replay to Terminator; Centaurs under Haghesh destroy 30-40 Knights and die in return. This is despite the fact that he only has 2 speed rings as good artifacts; I have 5 dragon rings, a speed ring with 10%, an axe with +4 attack, and a horseshoe. The attack and defense stats are many times higher. Both have Retribution. I'm saying it again - the horses destroy a stack in return and continue running... Frightening is not an option; his hero moves 2-3 times more often than my hero and catches up (or uses mass spells). Now I'm trying with Mages, the Hive, and Darkness.
