Okay, my original understanding was that they would give you up to ten CP per vet rank on your highest character if you didn't already have them, and that each vet rank would count as 10 CP. So, if you had a vet rank 14 character and didn't already have 140 CP, you would be bumped to 140 CP and still be able to wear your old vet 14 armor (which would require 140 CP to wear).
But looking at the PTS patch notes, now it's saying 2.5 CP per vet rank for your highest character.
So I've got a PS4 character with well under 70 or 80-something CP at vet rank 11 (wearing vet rank 11 armor) and a PC character at vet rank 5 (wearing vet rank 5 armor) with about 35 CP. So will they both be naked when I log in (unable to wear their armor) after the Dark Brotherhood patch?
