Discussion about Heroes 4.

Unfortunately, in the fourth game, the chain spell changed its nature, becoming a teleportation spell for heroes to any explored locations. The chain spell is also quite questionable, which is what professional players take advantage of.

Could you elaborate on this point? Is there some trick involving combining a hero with units that have low movement points and are spread across the map? Or is there something else that I missed? Yes, I only played the vanilla version, as both attempts to install the expansion were thwarted by the heroes' persistent refusal to launch with it.
