can an official give an answer on to whether or not spellcasting requires a free hand in general?
it's never specified it doesn't, but at the same time it doesn't specify it does
example. it says spellcasting is basically entirely obvious, and all the spellcasters in the book show that they are using their FREE hands, but nothing specifies otherwise anywhere and people are freaking out trying to abuse it in ways that might not be intended
people are trying to use 2 handed heavy weapons, or any combination of weapons that fill all their hands, and then just cast spells because they think they can
and I feel this needs to be added to the FAQ that it SPECIFICALLY does or does not, none of this vague bs
