Why would you record voice sets for barks that won't be supported with the cinematics later on? How will the player know which voice sets are just to make EA more fun and which will be part of the full synchronisation? Sounds like a receipe for disappointments.
Again adding the full set of voices is going to be a lot of work especially in this case as there is no limitation to where voices are used. For example SWTOR had only the planet's story shared (and only per faction), but all the class stories had only 2 voices (male and female) to support. Most side quest had barely any longer sentences from the players. Now think what happens if you need to change content and suddenly for one line you need to call in a dozen voice actors? Also sounds use a significant amount of diskspace as they can't be cut in modular parts like graphic assets.
When it comes to supporting EA... I agree that most of the changes they have given so far are only interesting for a minimal group of players who think they are deeply involved into the development process, but for most of us there was no reason to replay the game. Personally I can barely make it through the inital squence of the game with a second character as there are a lot of things that make me cringe, but I'm trying to take the evil route. Sadly there is nothing except the evil quest outcomes that might motivate me, since in my first playthough I played a ranger and there is exactly 0 novelty in playing again. I know the classes, I can try different subclasses though only to a limited degree (some are ineffiencent, some are blocked as your cleric and warlock have them already choosen,...), overall it adds nothing to play the game a second time.
On the other hand I don't want the pressure on the development team to be 'ENTERTAIN US!' - they should be focused on the development. If they are willing to make real changes and it takes more time, I am all for it and a lot more interested in those results than having fun with EA. But so far its non of both. The game barely changed, my biggest gripes with the game don't seem to be at all on Larian's roadmap.
