This is a great list, the weapon damage specifically I've seen a lot. I have a Quasit familiar whose claw attack does 2d4+0 damage, yet consistently does 1 damage to enemies.
Additional Concerns
***********
The jumping mechanic, especially for followers. This is not a feature we had is DOS2 so it never came up, but if I have a group of 4 with an animal companion and a familiar, I have to individually make each one of the six jump over a gap to proceed. In addition, I have to be sure the group that has jumped over already is out of the way, or else there is no room. It is a very cumbersome mechanic and I hope they find a way to streamline it.
