Or perhaps they are saving the evil playthrough feedback for full release so that people who tested it in Early Access can experience something completely new when the full game is out?
Not really, some of the issues with evil playthrough are quite game breaking.
Example 1: you come to the gate and observe the goblin attack. What would evil characters do? Will they help? No, they don't care. So, you just stay there and enjoy the view how the goblins and defenders fight without any interference, i.e. you skip turns (if you're behind the hill then goblins don't attack you, or you can enter a stealth mode). And, of course, the plot immediately falls apart. The game always assumes that you heroically help the defenders and all dialogues include options to emphasize your role in protecting the grove. Everybody praise you for the deed you didn't do.
Example 2: also in the grove, when the druids deny you entry, what would evil characters do? Who are they to tell me what to do, right? You can just ignore them and they attack you for trespassing... And the plot again falls apart because the game assumes that it is you, who attack them on behalf of Zevlor even if you didn't talk to him at all, and they start attacking tieflings out of the blue. All the dialogues later no longer make sense because they loose continuity. At the same time if you just jump into the grove from the side, practically doing the same trespassing, druids just tell you to behave and won't attack... because logic wasn't there.
And Larian didn't fix it after a year... but hey, instead they downgraded graphics for low end graphics cards and made a game lag three times more than in the beginning of EA... This annoys me, but as I said, I've already made my money worth, so I can wait for as much as they need to fix everything and finish the remaining content.
