Arcane eye should be cast every day. Others also, it’s very much a planned class where you should be casting stuff before session even starts.I really enjoyed your guide since I prefer playing controlling rather than blasting Wizards. Thank you for all the effort you put into it.
For the Diviner I think a 5 Star rating on "Expert Divination" is too high. A little bit of extra arcane recovery is nice but it is quite limited as you need to have already cast a lower level spell first and there are not that many Divination spells you are going to cast during the adventuring day.
