(feel free to skip this part; these are just credentials)
I have a level 52 light-armored warrior specializing in 1h maces +shield and/or dual wield (depends the occasion), restoration, smithing, and enchanting (no points spent in enchanting however, didn't want to be too OP). I've beat the main-quest line / companion / bard / Dark Brotherhood (my favorite) / stormcloak / thieves / and college of Winterhold, as well as a lot of side quests. I've worked my way from Adept to Expert, and I now play exclusively on Master. I am struggling to find anymore quest, aside from meaningless bounty / scavenger quests. I have about 150k gold, and I primarily call Markarth home (coolest home IMO). I have 48/50 achievements on steam -- I refuse to get married (I'm not a role-player), and I am also not going around to each hold and getting a 1,000+ bounty just to get the achievement (Why is this an achievement?).
*It is important to note that these are all complaints are from me personally, and were an annoyance for my play style.
Now for my complaints:
Horses-- Absolute garbage. They are hardly faster than sprinting, hard to steer at times, and have terrible AI. Seriously, why is my horse leading the battle charge into Ancient Dragon battles? I finally had to sink Malog Bal's mace to Shadowmere's neck when he kept attacking things, preventing me from fast traveling. Also, why can't we attack from horses? I feel like this would be a VERY cool feature.
*One thing to note for newbs: Horses are effective mountain climbers, and I mean ridiculously effective. For whatever reason, horses can scale any cliff with relative ease.
Vendors-- Specifically in the early game. If you aren't in with the Thieves guild, selling dragon bones / scales / pricey armors becomes a pain extremely quickly. I had to map myself out a fast-travel route where I could sell all my equipment, as Vendors only typically have ~750 gold. Why does vendor gold scale with level like everything else? This should be implemented. Having to leave lucrative items on a corpse because you are filled with crap vendors cannot afford is infuriating.
Misc Quest- I've done 100+ of these. I would venture to say well over 70% are uninspired and unoriginal. These quest are primarily scavenger or bounty quests, rarely resulting in any significant compensation -- you'll find the occasional word wall which is nice. But honestly, for a company that prides themselves in engrossing and immerse questing, this was a major disappointment. I think -most- of the main faction quest lines were well done (with the exception of thieves guild, and the companion quest like which was entirely too short).
Bugs-- I actually had a good experience to some of the horror stories I've been reading on here. However, there is nothing like hitting f5 to save and having my game instantly crash. When doing an abundance of alchemy/enchanting/smithing at once, my game was prone to freeze once I exited the tool tip. Which leads me to my next point . . .
Enchanting station-- IT'S F***ING AWFUL! Really? Is this the best Bethesda can do? The entire interface design for the enchanting station is an absolute mess (at least for myself on PC).
Money needs more uses -- I have 150k in the bank and literally have nothing to spend it on. I think expensive armor dyes would be a very cool idea for upcoming DLC.
Loot system is bad -- It just isn't good. You don't find enough random good items. Almost all the best items (which tend to be artifacts or craftables) are scripted items given through specific sequence. I think the thing that made the Diablo series so fantastic was the ability for an amazing piece of loot to be on any enemy. It was appealing, and kept gamers checking every corpse. Now that I have so much gold, I don't even bother checking corpses that aren't apart of a major quest line, or the boss/final encounter in a dungeon.
Enchanting is broken -- I know many of you on here will defend Bethesda to the bitter end in regards to this, but the truth is, you shouldn't be able to become invincible by playing the game. It doesn't matter if you exploit the game or not, it isn't cheating, it's merely playing smart. Bethesda has even came out and said they are reworking some balance issues. Hopefully this is on the laundry list.
Some of the skill trees are useless when compared to the alternative -- see lock picking, pick pocketing, speech, and alchemy. I know some, if not most, won't agree.
Too many shouts More isn't always better. I would of much preferred for Bethesda to scrap some of these shouts, and get down to maybe 12-15 shouts with a 4th word to be learned. I probably frequently use 5-8 shouts out of the 20.
Now, after all that complaining, you are probably expecting that I think the game svcks, well I don't. I think it would benefit greatly from heavy patching, but regardless I give the game a 9.5 / 10. I will probably take a break from the game, at least, until some heavier patches come out. There really isn't much left to do besides level, and it's starting to get very difficult.
If you took the time to read this, thank you. I wrote this extremely quickly and it shows. If you have thoughts, I'd love to hear them!
TL;DR -- I took an arrow in the knee . . .
