I enjoy it when story and class are tied together, so hope Wyll's rapier proficiency is brought into line with 5e rules and is grounded in a class or feat on full release, and has only been bolted on in EA as it's required for flavour but whatever it's from in the character concept isn't implemented yet.
Eg In the full game Wyll could be a variant human with the weapon master feat. Or my swashbuckler rogue multiclass idea would give him a rapier proficiency too, though only I think if he started as a rogue then took warlock at level 2. Which would make sense in terms of his backstory but unfortunately not of the character creation process for an origin level 1 character as it feels like Wyll has to be able to start the game as a warlock for his story to make sense. (As a companion, of course, he could be level 2 when we meet him.)
