Horses, in general. Why they think horses will be mandatory if Mounted Combat is introduced is beyond me: WE STILL HAVE DUNGEONS! Not to mention there are plenty of ways to introduce mounted combat that will be balanced but not overpowered

I, for one, will be waiting with bated breath.

as always

Fall damage, and the fact the only thing to mitigate it is an armor perk
The fact that all enemies in late levels have shouts.
The ease at which enchanted items appear in the stock game
The fact that the stock game forgot to scale an offensive skill.. think we all know what I mean.
The commoness of Ultimate potions in the stock game, hamstringing alchemies usefulness.
The lack of any kind of agility (fixed speed, fixed acrobatic skill)
The lack of any kind of reward for low encumbrance and penalty for high encumbrance
The gutting of our spell abilities
The lack of spellcrafting.
The short short guild storylines
The lack of any finesse concerning the DB quests.
The lack of dialogue changes to NPCs as you progress
The lack of common error checking conerning weapon/armor lists (i.e. cant improve skyforge steel dagger)
The fact that no factions conflict with each other
The lack of choice concerning your stance with foresworn or silver hand or many other sub-factions. I wish we could start "neutral" to these clans
The fact that vendors are all operating off of 3 lists.
The fragility of dragons

I'll add more later.

- Skills are generally unbalanced, some arn't even worth being skills while others remove all difficulty and force you to play Novice if you use them.
- Claw "puzzles" are used way too much.
- Combat mechanics are dull and there is next to no skill involved outside of exploiting the dumb AI if you need that edge on them for some reason.
- Dragons are worse than Oblivion Gates, they quickly become a chore you can't ignore.

I like the gameplay, only thing that pees me off is how easy the game gets, its just not a challenge to fight and just becomes disinteresting.

the horses are way to slow ion this game
