Old maps’ spawning points aren’t optimized for the beastmen. They just spawn too near or in strange places.
Last time I was fighting a beastmen horde in HoM, in the room on the roof before the wooden bridge to the elevator to Magnus tower, and a gor hit me appearing from thin air.
Considering they deal a tad too much damage, their hordes are mainly gors, they have annoying features like the archers, IMHO they should be removed from all the maps, except the ones built with their spawning in mind.
P.S. I bet whoever designed the Bestigor charge had very low grades in physics.
