I always consider these "Why is everything so easy" threads to be just bragging. I just retired a level 45 Nord warrior with maxed heavy armor, block, smithing and a high one-handed, and dragons still were no picnic. An Ancient dragon's breath could take out half my health in one shot, even though I probably put over 1/3 of my levels into health. I'm not playing on Master either; Adept for that first character.
Because many people take advantage of the ability to become UBER and the moan when nothing is hard enough. Maximize smithing and enchanting and you can make a character with such high defense that he/she can go through a battle with an ancient dragon without a scratch.
I prefer to use the same equipment as the Dovahkiin posterboy -- that is steel Skyforge sword, Banded iron shield, Studded armor (Or scale, forgot which, but they look the same) and iron boots and gauntlets. On top of that, the OP could refuse to perk the hell out of his skills to where each shot with a bow deals 200 damage
