Physics in Heroes 5...

I found a bug in the physics model of Heroes 5, so to speak...
It concerns the griffin's ability called "Strike from the Sky."
Quote from the magazine "MIR FANTASIKI":
"Winged steeds are generally not suitable for close combat with ground forces. A griffin cannot swoop down on its prey like a hawk. To prevent inertia from crushing it against the ground, a heavy griffin will have to start braking long before it descends to human height. And it will slowly descend, belly-first, onto the spears.

Air cavalry will be able to attack infantry with slightly more success from a low-altitude flight. But in this case, griffins, to avoid hitting each other with their wings, will have to approach the target in a sparse chain. And they themselves will suffer heavy losses from the spears stuck in the ground. Flying creatures generally have hollow bones. And an eagle's skull is as fragile as a shell compared to a horse's skull."
What do you think?
