Support for multiple magical traditions
Needs functionality for having only the highest primary attribute for other entries' prerequisites and functionality for changing dependencies.
It is a great pity that this requirement has been removed. We have this situation right now. We are playing G7 with high level characters and DSA5 rules. Our "Firnelf" (magical tradition elves) has now decided to study in a mage academy as a secondary training and become a full-fledged guild mage. Here it would also be clear that there is "elves" one main tradition, for all rule cases where only one can be applied.
What do you mean by "this requirement has been removed"? TDE5 has never disallowed the use of multiple tradition; it just has not been clear, how this should be handled in terms of primary attribute and so on. But the editors (Alex) made clear, that the highest primary attribute is the attribute to use for all calculations and prerequisites. That is, you don't necessarily have a "main" tradition, as it may "switch" based on the attribute values.
Also, Optolith has never allowed buying multiple traditions, because the logic mentioned above has never been implemented and also is not that easy to implement, because there are a lot of area to track, since dependencies also include tracking unfamiliar spells during character creation (unless I want to ignore that and only allow finishing character creation if there are not too many unfamiliar spells, but that behavior would be different than how Optolith usually handles dependencies and thus not intuitive).
