One of the biggest problems for me right off the bat was the Magic system. To simple give you a bunch of generic tomes and then never allow you to custom craft spells is unforgiveable. That was half the fun of Morrowind and Oblivion. I am so glad there is Midas Magic at least for the PC community.
The whole magic system and the pathetic College of Mages is just annoying and a total step backwards for the game devs.
Removing the damage done to armor and weapons from use and combat is also a big deal to me. I am so used to just whipping out my repair hammer after combat and banging away at my broken gear. That was a major factor in the realism of the combat and battle of the last 2 games. I get hit by a freaking bear or Giant and I want my armor to get shredded like it would in real combat.
Limiting the enemy scaling to 25-30. That just kind of makes the game pointless after level 35-40. Even on Master it still gets pretty easy to get multiple kill-moves and savage kills on most enemies. I want to encounter bad ass enemies who will give me a mighty test of my battle skills and experience. A lot of people evidently wanted the weak and limited enemies. Thank Talos for Wars In Skyrim and a few other mods that add new combat difficulty and enemies.
I could keep going for a few more hundred paragraphs, but I think I made my point. I started with Arena, then spent a whole lot of time on Daggerfall. I have played well over 1500 hours of Morrowind and about 2000 hours of Oblvion due to a chronic disease I am suffering from. I guess that makes me pretty qualified to be critical of the new and stripped down ES.
I'll shut my gob now and try to help make the game better by posting to the developers and supporting the amazing modding community.
The realism part of taking your hammer stack between each combat and repairing your bow and your leather armor by banging them and breaking hammer after hammer after EACH fight is for sure such a good thing I can't see why Bethesda decided to get rid of it.
Oh and you should know that monster level goes up to ~50 and not 25-30, dunno why you talk while you obviously know nothing about the subject. For example, Arch Necromancers are cute little boys and girls level 46 with an earnest desire to melt your face off and raise your body afterwards.
