As I stated previously, I'd personally rather not have the BP in the game for various reasons. But it also won't completely break immersion for me if Relic keeps it. I can live with it, but I also don't get why Relic clings on to the BP so much.
That's pretty much my point of view, and probably original idea behind this thread (before it ended up comparison olympics).
As I was always saying, there is nothing wrong with BP being in the game if we look at CoH history, Relic might as well decided to add yet another layer of fiction.
My main complain, is that, if you read between lines, existence of BP doesn't even make sense considering how Relic wanted to present CoH3.
I mean, in one of the videos relic employees proudly said something like "We received feedback from a community, saying that US Rifles model uses wrong model of a jacket and we changed it"
The whole reasoning why BP should be in the game and especially the fact Relic protect the existence of BP is very concerning. I am 99,9% sure its not because "big tanks sell games" or because its cool or even I am not sure that it has any balance reasoning behind it, since (at least from file digs) there are no indications that DAK\Wehr would have anything heavier then tiger\panther.
In other words, Relic intentionally adding and keeping BP in the game, and most likely solely to allow more prototype units added into the game. And if this is the case, they would be either used as a selling point in DLC content or it will be used to plug holes in balance, instead of creating interesting asymmetrical gameplay.
