Now, I saw this topic and couldn't believe the title, and I want to voice my opinion unchanged by any other posts, so before I go through and read all seven pages, I want to voice it here and now.
1.) Dragon Riding - I agree completely. I expected to have them as horses (albeit some that I must still control by way of shout), and I had planed to ride one from Riften to Solitude and everywhere in between. I couldn't do that, and it truly did seem rushed I agreed with this one.
2.) Werebears - I want to play as Beorn so bad... I wanted to be a Werebear so bad... It was rushed, too. I partly agree, but I am thankful that they are even in the game at all, and although with Bethesda it is a stretch, they may have included it to have a working model to test reactions before the next DLC (optimism).
3.) Morag Tong - It is a common mistake with the developers misspelling it in conversation with that one guy in the Thieves' Guild (forgot his name), but it is "Morag," not "Morang." Again, it is a common mistake due to their ignorance (they needed a dev. from Morrowind to do that part and other things). As for not being able to join, they are mortal enemies with the Dark Brotherhood, so they would have to change the vanilla storyline as well, as they are in it, and that would take a long time, plus most people have already done the quests. They really should have made one able to join if they destroyed the Brotherhood or never joined.
4.) Apocrypha - I think they did fine on this one. Of course it wasn't open world - it houses forbidden knowledge, of course it isn't easy to reach. It houses puzzles and battles to stop the unworthy in their tracks.
5.) New Unique Amors - Although they added barely any of these at all, they ones that have are amazing, and the new enchantments on older armor are (excuse my pun) enchanting. I am satisfied with them. Furthermore, you seemed to have left out the praise on unique weapons. There are many of them, and the use of them can be quite fruitful!
6.) Spears - Spears were the biggest dissappointment... I hoped that they could be used as the spears from Morrowind. I would have even been slightly satisfied if you could throw them like the Rieklings do, but no, you have to shoot them with a bow... I hope they actually do include spears in the future.
7.) New Armor - The new armor was truly ment to bring back feelings of nastolgia and to fit the landscape and people alike. Also, it isn't a common occurrence that they add an armor that is so far above the rest. Furthermore, the way I see it is, if one's smithing and enchanting skill is sufficient, one could easily improve the armor past the limit; I did.
To recap, I agree with many of the things you say, but did you mention the large number of Quests? Dungeons? People? Even the uniqueness of the landscape? These are all small things that we complain about, when we truly need to look at the larger picture. That is the map of Solstheim; it's a large picture! Anyway, I think the DLC is great, and given the circumstances, we need to thank Bethesda for actually giving is a historically withered, geographically correct, and simply beautiful recreation of Solstheim; not to mention the fact that they even gave us new armor, weapons, enchantments, spells, and powers!
Anyone with deep agreement or disagreement (or if they sparked anything in your mind) of my own thoughts, I ask you, please PM me to tell me what you think!
