I don't like mages, as in pure mages. Boring. My Altmer character was the closest I've ever come to playing one.
Vampires... literally the only reason I've ever become one is that I wanted the achievement for maxing out the Vampire Lord tree, in both versions of the game. And I reloaded/stopped playing the saves after finishing that achievement (right after Harkon turned me); I'll never go against the Dawnguard. Isran is the best, one of my favourite characters in the entire game.
Vampires are disgusting, bloodsucking abominations that need to be eradicated.
I've never done any crafting loops, especially the broken fortify Restoration one. Also boring. I almost never use any kind of fortify Smithing/Enchanting/Alchemy potions, and enchantments for those three are ones I never put on anything.
I practically always play on Adept (extremely rarely on Expert) but I find ways to make the game less easy by implementing restrictions. Master and Legendary are just stupid because of how the "difficulty" is nothing but massively boosting enemy HP and damage. Much more interesting to, for example, only use weapons, armour, and/or potions you craft yourself (this is why my Breton still wears leather). Doesn't even require mods, and your creativity is the limit.
Mods, of course, add a whole new world of possibilities, but vanilla Skyrim offers plenty by itself. That's why it's still almost my favourite game of all time -- second only to Witcher 3 -- even after over 8 years (I only got the game in late 2012 or in Jan 2013).
That almost vanilla playthrough of Oldrim I mentioned in September? Tons of fun despite the almost complete lack of mods (the vampire attack disabler mod doesn't even really count considering Bethesda themselves removed those attacks in SE).
