Book-Friend, he/him
It's already specifically 2.I'd even argue that the following would yield much more reliable results, forget all the 1 to 5 and how to interpret them nonsense.
1) do you prefer this over the 2014 version yes/no
2) if yes, is it good enough as is yes/no
That's it. Given the playtest experience, you should rate everything 5 you want to keep and everything 1 you do not, anything else is you fooling yourself / screwing yourself over.
Rating something 4 and then giving some qualitative feedback works, too. 4 is over 70%.
