the experience of arena off-tournaments on the League shows that a mage in the endgame is preferable to a warrior in most cases, even with upgrades.
How so? I don't know which arenas were used there, but it sounds very doubtful.
Vik, I don't understand what this obsession with morale is about. Is SoD primarily about morale-based neutrals for you?
As for the blacks—it depends heavily on the player's skill when they will appear and how many. This, by the way, is the main argument against the idea that morale gets in the way, mages are non-viable in SoD, etc.
Все в ней нулево и кукольно.
