Heroes 6 - Discussion

Dreamcatcher (Dream Thief)
Orcs pray to Mother Earth and Father Sky, and Dreamcatchers are the voices of their ancestors. To become a Dreamcatcher, a shaman must first embark on a dream journey through the Spirit World to meet the spirits of their ancestors. During this inner journey, the Dreamcatcher must also confront their own demonic heritage and destroy the Chaos within themselves. Many Dreamcatchers die during this trial. Those who survive return changed: their bodies are scarred by the struggle with chaotic blood, but their minds are filled with a greater understanding of blood magic and the spiritual realms.

Now, the question is: are all Dreamcatchers shamans, judging by the description? Yes.
Question #2: Are all shamans Dreamcatchers? No.
A Dreamcatcher is the highest caste of shamans, and a special ritual is required for the transition. At the same time, the chances of successful completion are small, and the price of failure is high (the shaman dies).
Plus, question #3: What will be the name of the hero-mage class in the Great Horde (and will there be hero-mages)?
P.S. While I was writing, Arandor already answered.

UPD
In general, the names of units should not contradict the description in the first place, and common sense in the second. In that order.
