I kinda want to Necromancy this topic in lieu of the new update.
In particular they fixed the issue with bitter divorce and added some new spells.
But I am curious before doing any testing, does Flaming Sphere have any unintentional interaction with Find Familiar like how Mage Hand did so, since Mage Hand and Find familiar dismiss eachother?
Also new thought after more playing:
Familiars should not have their own turn, and neither should mage hand. Because of their low level nature, they are supposed to use the summoner's actions to attack, making them more balanced. As they are right now they bloat out the turn order and action economy. Furthermore, Mage Hand being summoned in combat had an issue for me where its turn didn't happen because it entered late which then made the spell a useless action.
Lastly, I would love to see eventually them add summoning and conjuration spells from other editions so that I can play a summoning warlock or wizard.
