I think this approach of focusing the EA on evil playthroughs is not a good strategy for the game. It runs the risk of making the evil path default for the game, because that's what will get all the iterative improvement attention. Even the good aligned companions won't show until after EA, and so won't benefit from that iterative improvement. A good EA strategy would allow a representative slice of the game to be iterated and not just one particular way of playing the game.
I sincerely doubt that the "evil path" will be the default for the game. It's pretty clear historically and on these forums that players prefer to play the good path. This is a mass market game with a mass market audience, and going with the evil path as default would 1-harm sales, and 2-be very unusual. I think if they were going with an evil default you would hear about it in the marketing, because it would be a fairly unusual narrative choice.
