The Norn epigraphy is based on the Northern European cultural form of inscription, also known as runes.
Dissatisfaction with a flowing language is likely the product of Norn psychology, which is shaped by a prolonged pattern of life. The Norn are hunters, warriors, and conquerors of the harshest elements. Their way of life is conducive to that of a bear’s: prolonged state of waiting, or hibernation, followed by sudden action, or, in this case, hunting. Consider hunting, itself: It is a process of patience followed by decisive action.
That the Norn have more than one word for hunt is no surprise! The climate of the homeland of the Norns is not conducive to farming on any scale. The entire Norn culture has, presumably, hunted and consumed game, animal flesh, for thousands of years. This would explain the large and durable Norn physique, as well as their honed combative instincts.
The problem with this is that game is eventually hunted to extinction, and, like the Northern Europeans, settling arable land will become a priority as the Norn population is no longer supported by the game of the frozen lands.
A real world example of this natural process is encapsulated in the aurochs.
If the Lore of Tyria follows the lessons of the history of our own world, part of the Norn will one day merge with a race inhabiting arable land, likely the Humans. It is also possible that the Norn population never reaches the critical point wherein hunting is no longer able to support the population; this may occur due to a population decline, such as from war, famine, or other catastrophe.
