On the earlier more ritual spells thing... I notice at least one new ritual spell (silence) but it's only on the divine & primal lists. The arcane list ritual spells look the same based on a quick skim. All three lists have a good number of spells with a school shift though.
A pawn with their free sample.
- Chain pact: Maybe just a regular familiar till level 3 or more. Frankly having an intelligent at will invis familiar that can change shape is kinda bonkers given how much of a nonissue it isa to have a familiar get killed in 5e.
- Blade pact: You are proficient with martial weapons & can choose a first level fighting style from the warrior group. some of the rest comes in at 3rd
- Tome pact: Too many unknowns.
- Archfey: You can consider faerie fire & sleep prepared The rest comes at 3rd (or maybe vice versa)
- fiend & Goo, similar to archfey
Edit: This is assuming eldritch blast is going to become a warlock class feature based on warlock level as everyone suspects based on the lack of it being in cantrips
