Alignment is NOT a fundamental pillar of D&D...at least not in 5th Edition. The current edition has moved away from this to promote personal character motivations/actions over taking action based on alignment. Alignment was largely arbitrary anyway.
The Warlock's Find Familiar only produces new types if they take Pact of the Chain at a higher level. This should be explained at character creation. It should be clear when certain abilities and subclasses come online for players not familiar with how the pnp class works.
I do like the idea of a schedule, or a list of priorities Larian is working on, but with Covid still being a major obstacle, I'm just glad we have early access at all.
