I do like the idea of having a small handful of unique summons and spells.
But while the conjuration spells could and should be better than default conjuration summons,
Then i do agree on that combat spells most of the time should only be situational useful.
With of course noteable exceptions like the Marveni Tatoo ones.
Or i guess the Xibalba soul ones are also an example of national spells done right.
