Some Extra Ideas (with the help of my friend)
MagicDifferent types of atronachs:
Maybe Wind, Water, Earth (basically all elements or just mix it up a bit with different summoned creatures)
Spell creation
More spells available
More variety of staffs and mage clothes etc.
CombatMore varied attacks (rather than just left right left right etc. although the power attacks are good)
More weapons e.g. throwing knives, throwing axes, spears, halberds, slings, crossbows, javelins, different kinds of swords (rather than just sword and great sword), shuriken type weapons, flails, different maces, more varied bows (short bows, longbows etc.) and hunting bows and bows with specific purposes that actually are suited to certain activities.
Improved hand to hand combat and the ability to disarm and critically injure enemies (locational damage etc.)
ArmorDifferent sorts of armor and more unique for the wearer (as stated in my previous post) and the ability to customize what you make (including weapons).Ability for armor to become damaged and worn down and have to be repaired unless it is fully wrecked.
Capes and cloaks, different types of helmet (full helms etc.), more armor slots (more places to put and have armor on the body to increase armor or mix up heavy and light).
Before being able to craft race specific armors and weapons, the player must first visit a smith of that race or someone with the knowledge instead of just leveling up and automatically mastering the art of another race's technology.
MovementAdd the ability to grab and/or jump onto objects and climb up things as well. Also the environment should affect how you move e.g. thick snow slows you down especially in heavy armor.
Armor be able to affect your movement as many people say e.g. wearing full iron armor and sprinting effortlessly through The Pale NO
wearing heavy armor and struggling to move with any significant speed through The Pale YES
Cities/SettlementsMake cities bigger. There are probably going to be more people than in Whiterun in an actual city. I find it hard to think I'm in a city environment when there are barely any buildings or they are just not at all obvious. To be honest they are all more like towns.Different kinds of shops. In every major settlement there are exactly the same types of shops (blacksmith, general goods, food stalls, inn, alchemy) but I think it would be much cooler if there was a wider variety of shop types with perhaps individual items to sell according to that area. I don't know the details but maybe this would spice up the game a little.
