Artifacts in Heroes 5

I urge everyone to buy a license! My game was lagging, but after I purchased a license, it started running smoothly! And the artifacts aren't bad; they're not as overpowered as they used to be. But the fact that the "lucky horseshoe" can now be equipped on a foot(!) means Nival needs to be punished!!!!

In my opinion, everything is correct. Demons with hooves, humans on horses, elves on unicorns, and necromancers on zombie horses are all present in battle. The only ones who can't equip the horseshoe on their "mode of transportation" are the dark elves (because they ride lizards) and the mages (on elephants).
