I have so many builds to explore all the different niches, and ways to beat the game. Spellsword is one of the best, because you've got medium range, and close quarters covered, and you don't have to switch between them. I've been doing spell/shield combos lately, because I like the extra protection of the shield, and staggering from Bashing. Really makes up for being low armor for robes, and health for magicka.
One that I don't do is epic tactical crafter. For one thing, I don't have the patience to grind up 3 skills, much less do the potion/enchant fortify skill loop. I like to play the game, meaning quests, and combat, not spend hours preparing to break it, and once a character becomes OP, I get bored, and start over. There's lots of ways to enjoy Skyrim, but this just isn't fun, for me.
