I like to use the weird spells that players rarely take due to being less than optimal. That way they still get to use them situationally, without having to “waste” a slot.
The exception is when there’s a particular story reason for a certain type of item to crop up; for instance, a group of assassins hunting a powerful mage might have a lot of dispel and antimagic type things.
Not a very high quality article. Makes constant reference to “faction and domain play” without adequately defining the terms for someone that didn’t grow up with them. (Presumably, the target of the article.) And a lot of typos.
