What it will take for me to purchase Dom III

[Chazar]

I dont like the course of this discussion: National troops should not be more powerful, neither should summons be less powerful. Summons should be powerful and become slowly more and more abundant as the game progresses.

However, allmost everything in the game is capped by either a hard limit or by some sort of upkeep (gold,supplies,...). So why should the majority of the summons be exempt from this upkeep principle?
