Well in past three weeks I was doing this small "research" about difficulities, and I think I found easiest mode for those who cannot go further then Adept.
Some people are perhaps ashamed of it, but there is no reason. I know people who have problems with everything >Novice, well, don't know all of them personally but people do post about their problems with difficulty. Some people are good with FPS, some are good with RPG, sme play PES or some racing game, etc, so there is really no shame about having problems with difficulty in this game.
Basicly this build is the easiest one to master so far (by my opinion ofcourse), and currently I am 33 lvl on it, and I really have no problems with single fight with any kind of mobs/dragons.
To make it more fun, I just defeated Krosis + Blood dragon at the same time on Master, and I used few pots, mostly for stamina. I am really not pro gamer nor I started from Master difficulty, I started with Appretance and struggled a lot untill I decided to go for Adept and above.

Basicly, the easiest build so far for me was this;
Block/One-handed/Smithing/Heavy armor

Block - Fill basicly everything up but the last perk. It is up to you what to do with it.
One-handed - 5 points for twice damage in total (First perk).
Smithing - Go for heavy armor and level it as much as you can.
Heavy armor - Same as Block, everything up to last one, that one is your call, but it is not needed too much if you're good with blocking, rather save that point.
You will have 15+ more perks to spend wherever you want them.

Secondary;
Enchanting - Just for 25% more on skills
Restoration - Reduce magicka cost for novice, and get that perk which provides you with restoring health + stamina
Speechcraft - Reduce some prices, you will need it later on.

I'd go from 1-10 = Adept
10-20 = Expert
20+ = Master

*Spoiler*
Items to get before Master;
Spellbreaker - I don't care much for it being dwarven, 50 points spell negation is just epic, doesn't need recharging, and whenever you stop blocking and then block again, those points refresh. And as you have smithing, do upgrade it.
Dawnbreaker - Very very useful weapon against undead. Since you will most likely run into loads of them in dungeons, be sure to have it on Master difficulty. There is a good chance once you kill undead with it, he will explode and cause havoc and fear to nearby undeads aswell, who will get damaged and run away. Upgrade it.
Sanguine Rose - This is very good staff for Daedras, those crazy minions really tank and spank your tougher opponents, especially good for spellcasters. It will probably save you more then once.
30+ lvl - Ebony mail, defenatly. Just a lovely armor with good stats, upgradable when you get your 60 lvl smithing perk for upgrading enchanted items (You'll need this for those items above ofc). It will glow when you enter combat and it will harm your enemies with not so epic aoe damage, but it will do. And good thing about it, even before your music starts or you see enemy on your compass, armor will start glowing, so you'll know someone is there.
*Spoiler ended*

My warrior here is a Nord, and he has 50% cold resist. It is usefull vs all kind of frost buggers, but; Be sure always to have fire/frost/shock ressit on appareal, be it boots, rings or necklacess, makes no difference, buy them or just enchant them, it is your call. This goes very good with Elemental Protection, reducing all magic on you by 50% while you're blocking, and with 30-40% extra ressist on certain school of magic will only scratch you. And if you have 50% ofcourse, it will not harm you.

Basicly the most important thing is to block all the time (Naturaly) and once you get Quick Reflexes with Block runner, combined with Conditioning from Heavy armor, you will never be hit by power attack again, since slow-mo + moving quickly is just awesome.
Yet, if you do play on expert or master, try not to have 5 enemies on you at once, try to scatter them, Thu'um or follower, anything really. You most likely won't die, but there is always a good chance if enemies are above mere bandits.
Dragon fights will unfortunately be very boring and you will be OP against them. You will take no damage while blocking, with proper blocking + ressist you will take no damage from their fire/frost. Just block, and shield bash them, they will stagger, and if you use sword, you will be able to hit them 3 times. Then block + stagger again (Good for interrupting aswell). Repeat the process and basicly dragon will fly off, and come back to you. It is quite easy tbh.


So, I think this is basicly easiest possible built to play, at least by my experience, so those who have problems with difficulty, might just try it out, or add few of their bits into this and finally challenge Skyrim on harder difficulities, which, well, will surely encourage you to play with your old toons and new ones on that difficulty once you get some selfconfidence.

I hope this helped a bit.
Cheerio \o

Fixed now.

Unarmored dagger using sneak character that puts all stat points into stamina, beats everything except for dragons on master difficulty. (smithing needed to get enough damage, as well as the dark brotherhood hands)

I find leveling Smithing, Heavy Armor, one-handed, Block, and Archery, and leveling up only health ever level will make the game much easier. Enchanting and Alchemy helps out a lot as well, and you don't even have to loop it to be amazing.
If you're cautious, then you can be an OP assassin by mixing sneak, illusion, and one-handed. You never have to worry about getting hit as you get a croud of monsters to kill each other while you one shot the victor. Dagon's Razor is a keeper.
As for Stones I recomend the atronach or the Lords stone. I'd have more detail but I'm falling asleep.
PS the Breton and Orc are amazing races

Well I prefer sneaky style aswell tbh.

But this style is very easy, and it allows you to actually charge into mobs, with no fear of being discovered. I am not saying people on low difficulty level are not good, but I think for starters it would be better if they can walk trough enemies and have high survivability, then go right away with assassin, be all scared of Master, one shot someone and then get killed by crowd. I think people have problem with higher difficulities just because they think they -can't-, and I thought this would encourage them, after they realize they killed Frost Dragon without having to hide or use pots.
