Which is stronger, a Castle or a Conflux?

2 Sforza: Okay, let's examine your example about the Conflux mage. Why do you say that only magic power and knowledge increase? For example: Initially, the hero is Inteus (skills are obviously 0 0 3 3); level 2 - attack +1; level 3 - magic power +1; level 4 - attack +1, and so on until level 10. The result: we see the initial skills are 3 0 7 2, i.e., we draw the corresponding conclusions... I'm not arguing that the skills of "warriors" are most favorable for capturing certain buildings (dwarven mines, necropolises, etc.) or that in a scenario where the number of units is significantly small, mages will take the lead, i.e., everything depends on the situation. I was interested in the question of why you consider Conflux mages to be better than Castle mages? Did you really base your opinion on the fact that: 1) the initial skill (earth, air...) is already present? 2) mana costs are lower? Is that correct?
