Just two things Sawyer wrote in that post above:
Being required to find/save Imoen - I didn't like it then and I still don't. I wouldn't make the player rescue an NPC with whom he or she may or may not have a positive relationship. It's a very specific plot point and easy not to do. I understand that a lot of people have no problem with the rescue plot, which is totally fine, but I don't think that particular plot point need to be repeated in PE.
I sort of agree with this and Bioware confused themselves with this plotpoint, and bungled it all up. But straight after Imoen is taken and in the first few chapters they
don't present Imoen's rescue as a requirement at all, they instead leave it up to the player what the primary motivation is of tracking down Irenicus.
This is pretty clear from the dialogues selections where you can choose your motivation to raid Spellhold as either avenging yourself on Irenicus or as saving Imoen.
There are even dialogues to off-handedly dismiss Imoen's plight, like for example when talking to the first Shadow Thief contact (Bayle).
The problem is that when you at first confront Irenicus in Spellhold Bioware suddenly FORCE you to care deeply for Imoen and so they rudely override the player's motivations up to that point. Then when she is freed they let you be cold and heartless of a childhood friend again by either ignoring her before you run Bodhi's gauntlet or by telling her to escape by herself.
So Bioware just got lazy or whatever and once again its just an illusion of choice like most of their "role-playing" dialogue in all their games.
Being flooded with quests in Athkatla - To be honest, I don't think this is a controversial opinion! I've seen many other players say the same thing. BG2 has a crazy amount of quests, which is great, but the density in Athkatla was a little too crazy. I think those quests should have been spread out of staggered in some other way. PE is going to have more of an exploration focus than BG2 (though not as much as BG), so I believe that will help spread out the content more.
I sort of diagree with this, I really enjoyed the density of the quests in Athkatla. The only problem is the way these quests were presented to the player: they were a forced interjection.
It was only when you had a few quests going through your mind and then got within proximity of a quest giver who would then verbally assault you, that things got facepalmy or a bit hectic.
Otherwise, I think they mostly succeeded to convey the hustle and bustle of a city teeming with activity and intrigue.
Athkatla felt alive, more alive with criss-crossing quests than 3d cities with popamole "Radiant" AI anyway.
So I guess if PE has cities with quest density akin to BG2 I wouldn't be put off at all, providing they weren't all forced on me.
