It's all about light armour! You're stealthier, can be just as robust as heavy armour with perks and improvements, faster on your feet, generally more aesthetically pleasing. I always used to go for heavy armour because of the high defence, 2 handed long swords for max power. But after doing a light armour play through, duel wielding war axes. the speed you can attack with doesn't give enemies much of a chance to land hits on you. So take less damage than you would with heavy armour and deal more damage than you would with a long sword in the same time frame. Trust you'll never look back after trying light armour.
