That pretty much says it out loud for me...
my level 81 profile is a master at all crafting skills (enchanting,smithing,alchemy)
and is wielding weapons that do over 150+ damage each as a duel wielder. so i'll maybe just make a new profile or if im to desperate to play it all for the first time i'll just wear normal non enchanted armor like steel (witch is one of the best looking armor's anyway) and maybe move down to ebony weapons or steel. then pump up the difficulty to legendary..... sounds like it might be a challenge.....
I also like to stick to a lower level armor set to keep it more challenging as well and will play through the majority of the game using leather armor simply because I like the look of it. While I normally make use of smithing or alchemy for my various characters, I never use crafting exploits either and tend to stay away from enchanting completely for the majority of my characters. I stay away from boosting my crafting skills with potions or enchanted items for as well because it makes the game way easier than I like.
For the most part, what I rely on is mobility, target selection and the optimal use of my surroundings to overcome enemies. I pay close attention to the way enemies telegraph their attacks, my positioning within the surrounding area and the positions of any other enemies nearby to avoid being backed into corners or getting ganged up on. I also try to keep myself positioned in ways to minimize exposure to enemies using bows, crossbows and spells. I also always try to mentally predict how many attacks (according to the speed of whichever weapon I'm using) I can get in before an opponent will strike back. I am usually correct with my predictions and can either evade or block the retaliatory strike according to how off my timing is and the type of opponent I'm dealing with. Bears are tough for me for this reason as they attack so quickly sometimes.
My main character is currently something of an alchemist. So for this guy I do use lots of poisons to boost his effectiveness in combat. In addition, I'll keep anywhere from around 60-80 health potions on him just in case things get hairy. Other characters I try to make the most effective use of shouts and abilities.
I don't use exploits and if I play on hard or legendary I usually don't last long against multiple draugr deathlords with ebony bows and arrows and the unrelenting force shout.
If you think numerous draugr deathlords are tough try taking on a room full of draugr demigods
(a draugr type introduced from the enhanced high level gameplay mod).
