They wanted to make (neccessary) changes to the Ranger. This one seems interesting. A familiar you can use to explore and attack works for me. Not sure if this is going to the only the ranger´s or the entire "find familiar" spell tho. In the description still says familiars cannot attack and has to be in a 30ft radious so I assume it´s different for rangers, because in the gameplay they showed us it´s not.
Sadly there is no ritual casting in BG3 as of right now. (Sc: the Reddit AMA Q&A) so it makes sense to make it a cantrip. And there´s no help action either, at least in the EA, so I assume having an attack it´s a feasible replacement.
If the find familiar of the ranger is different from the standard spell, changing the name would be logical, indeed.
PD: Love that they're using the metric system in the game, btw.
