I would love to see some new content for the guilds, specifically the dark brotherhood. I would love to get involved in some more serious assassinations like assassinating a high priest of the divines (there has to be one right?) and making the way of you eliminating your targets more difficult such as no witnesses, public kill, murder in a specific house or home, etc. Also since I am still remaking the brotherhood I would like to get to name my own Speakers. Nazir and Bobette are 2 obvious choices but I would like to quest for the other 3 myself. I also need to know the names of the initiates (and hire more murderers) that I am working with if we are to have a good work relationship.
New armor ideas- dragonhide armor, Aetherium armor (hope you'll reconsider this), more falmer armor designs, light armor version of all heavy armors and opposite, Unenchanted Ancient shrouded armor (or some other kind of assassin's armor) with
face mask for males. Would like to see a more variety of clothing added to the current one.
New weapon ideas- two-bladed sword/axe/mace, flails, Claw weapons, Spears, slings, throwing spears and knives, darts, dual-wield two-handed weapons.
I would also like to get involved in a really long, dark and challenging dungeon filled with deadly magical traps like turning you to stone and crushing wall traps, very dangerous other worldly creatures like fighting angelic demons (maybe winged twilights and golden saints?), and other seriously life-threatening obstacles with some really insane treasure at the end of the dungeon like piles of gold and lots of boss-level chests. Would also like to see some really difficult puzzles and under pressure situations put into dungeons (look at Batman: Arkham City and the riddler's puzzles).
Would also like to see some "new" daedric artifacts aside from the older ones and an artifact version of every kind of weapon in-game.
And lastly, I would love to get involved with the great war between the empire and the Thalmor and join the Thalmor and running into larger battles between Imperial and Aldmeri soldiers. So much time has passed since I started playing the game and its time for the war to begin!

Thank you for reading!
