Tuthrick: - Dragons - don't like them in pretty much any game. They're overused and boring. Fighting them pretty much always doesn't make sense, why don't they just burn the group from above? I would prefer if in the game there was just one dragon and you can't even fight it that's how poweful it is, just like the Lady of Pain.
- Romances - borderline cringe. I prefer simply companionship between characters than a love story, ugh.
- Irenicus / main story - too much emo (trying too hard to be dark) for my taste. The whole Shadows of Amn feels like a huge sidequest from the Bhaalspawn and Alaundo's prophecy.
- High level mage combat - makes most other classes than a mage/sorcerer almost useless.
- No useful thief NPC, overall a small choice of potential party members. Yes, they're more developed, but this is no PS:T, where you can talk your way out of most situations.
- The artstyle in general: character animations (I still can't wrap my head around the fact that they've made them way inferior to the previous game, they're even mirrored), paperdolls, portraits, areas (why co many circles?), items (why so many spikes?).
Not trying to convert you or anything, but I just thought it'd be nice to share some discussion over your points. :)
1. Dragons - This I actually agree with! I have yet to play an RPG where I felt they did dragon combat exactly right. So far the closest they've come is the battles against the High Dragons in Dragon Age: Origins (the dragon combats in DA2 and onwards feel a bit too... "action movie" for my taste), but even so it does seem a bit strange that the Dragons, as intelligent as they are, wouldn't simply take to the air and just constantly strafe the ground with their breath weapons and spells until all opposition is destroyed. (I fully admit that it's due to limitations in game engines and "that just wouldn't be fun for the player" reasons, but the DM in me will always be vaguely dissatisfied with dragon fights as a result.
2. Out of curiosity, have you/would you play games that have romance as a central theme of the gameplay (i.e. visual novels) or do you just prefer not to have romances in your games at all?
3. Ironically, you might actually like the SoD's depiction of Irenicus more than the SoA version. In that game, Irenicus is more of a "mysterious stranger" who seems almost beneficent towards you. (Outside of one particular travel encounter, that is.) He provides you with small hints and information that assist you in your quest, and while he may chide or berate you for certain decisions, he seems to want you to succeed for some inscrutable purpose. This is a bit strange considering his goals and motivations in SoA, as if he'd taken a sudden turn for the worst towards Evil. SoD Irenicus seems more "callously Neutral" than outright Evil.
4. This I would say is one of the biggest weaknesses (although some might call it a strength and a selling point) of the 2nd Ed AD&D system; different classes peak at different points in their levels. Rogues and archer types tend to be crazily dangerous at lower levels, while Mages tend to be nigh-indestructible at high levels if given sufficient preparation. While I think that this affords AD&D a unique experience between classes ("Yeah, my mage sucks now, but just wait till I hit level 20!"), I think that from a gameplay and design perspective, it is not an ideal system for constructing a well-balanced RPG, because it means that, at different stages in their play experience, there will be players who are going, "Ugh, why am I struggling so much? This game isn't fun anymore!"
5. I do agree that outside of Yoshimo, there's no real great Thief candidate in BG2 unless you're playing EE (and have access to Hexxat, but she's obviously also out of the running if you're a Good character). The upside is that you generally don't need Thieves beyond a certain level and Imoen can fill in in a pinch when boosted by spells and some potions, but then again, this goes back to my point above about certain classes peaking at certain points.
6. I didn't have many complaints about the artstyle in BG (I liked the BG2 portrait style much more than the BG1 style, for instance), but if you mean that armor and weapons tended to look abnormally spiky or with too many decorations (like the various enchanted staves) to be actually useful in combat, then yeah, I do agree with you there. I like my gear to look stylish, yet functional, not overly exaggerated.
