We are leaning towards the solution implemented in Fresh Mod. Maximum 4 rolls and making it impossible to get control spell without a roll should reduce rng factor.
A question arises about what to do about library in tower, should it be counted as a roll in above logic? If so, the building will become significantly stronger. A suggestion for balancing it out is adding a requirement of mage tower before one can build the library.
If the library does not count as a roll, then building it before rolling for the first time becomes less desirable, but building it after at least one roll still keeps the role of increasing chances for control.
Another thing to consider is magic university in conflux. It is a very strong special building, especially on XL+U, and the cost of buying magic skill in it is not very high. We would suggest increasing the price of the building by 5000 gold and reducing the number of purchases to one per day.
Another issue around control is tier 4 spell shrines, both on mirrors and other templates such shrine with tp gives us a huge advantage over the opponent. We suggest removing an option for getting tp in that object. Getting some other lvl 4 spells can still provide a large advantage, but it will be partially balanced by the other changes.

Some changes to mage guild are necessary. The difference in obtaining control spells often determines the course of the game on more difficult templates.
We agree with the solutions proposed in Fresh Mod. A maximum of 4 rolls and making it impossible to obtain control spells without rolls should reduce variance.
A question arises about what to do with the library building in tower: should we count it as a roll? If so, this will significantly increase the value of this building. A suggestion on how to balance the library is that building the mage tower should be a prerequisite for building the library.
If we do not count the library as a roll, then building it before any rolls at all becomes less desirable, but building it after at least one roll still increases the chances of obtaining control spells.
We would also like to draw attention to the magic university in conflux. This is a very strong special building, especially on XL+U, and the cost of buying magic skill is not high enough. We would like to propose increasing the building's cost by 5000 gold and limiting the number of purchases per day.
Another aspect regarding control concerns shrines that allow learning a random level 4 spell: on mirrors and other templates, such shrines with tp give a huge advantage over the opponent. We propose removing the option to obtain tp from this object. Obtaining other level 4 spells can also provide a significant advantage, but this building will at least be partially balanced by the proposed change.
