Yes, I agree about this, though 15000 letters "alphabet" seems too much - Chinese has fewer! It would, of course, explain magic being rare...
By the way, could I look it up somewhere?
Important links vulnerable to destruction seems quite right for me, but what I'm not sure about is a possibility of making a random/semirandom NEW units production under the existing engine. IIRC mod commands allow either 'summon allies' which produces 1 type of such, or domsummon which can produce a few types with probability depending on Dominion.. This can probably include various types, but not with equal probability of each, so a variety of high-end types isn't achievable. They would also become rather common in high Dominion - and if they are free, then their production becomes completely automatic after the start, without any meaningful choice on a part of player...
