Plus, the minute you decide to level both Smithing AND Enchanting youve just broken your game.
I wouldn't say broken, it depends on what you want. If you ask me you should be able to see what is coming as you level these skills and keep putting perks into them.
I decided deliberately to make my third character overpowered, he goes like this: Smithing, Enchanting, Heavy Armor, Two-Handed, Conjuration, Restoration. Right now he is roaming the land with his wife, two Orcs dressed in legendary Orcish armor, his with Fortify Two-Handed and Fortify Conjuration enchantments, her with Fortify Heavy Armor and Fortify Health Enchantments. They are accompanied by a zombie thrall Bandit Chief or a Dremora Lord. It is just kind of funny steam-rollering over everything in a rain of blood (on Master). They mostly do quests for fellow orcs, or bounty missions for Jarls, or just wipe out bandit camps, Forsworn camps, or whole groups of giants and mammoths.
