Advantages of Mages over other races.

Vaishan, sorry if I didn't quite understand the meaning of your post. In any case, gargoyles won't cause any significant harm with their 1-2 damage. Therefore, in my opinion, eliminating gargoyles with centaurs is just a matter of time. Moreover, other orcish troops (for example, warmongers) may be nearby, and they certainly won't give them a chance. Although, the "stools" will still fulfill their purpose, blocking 1-2 shots. In the end, if you really want to, you can send battle centaurs into melee combat, ignoring the gargoyles.
