Welcome to TES series! I'm guessing Skyrim is your first TES experience because it's actually more restrictive than the previous titles in which you could create a master of all archetypes with one character. If your goal is to build a pure mage, then by golly, Miss Molly, you should eventually create a super mage. If your goal is to build a pure fighter, then by golly, Miss Molly...
What exactly are you complaining about?
Guy decides mages are OP based on more or less "exploiting the system."
Guy thought it was ACTUALLY worth posting, even though it's not.
Nobody is forcing anyone to use exploits.
It's not even an exploit if you ask me. It takes time to build your mage in the way that he's describing. Enchanting is a legitimate skill tree and if you spend the perks on it, then by golly, Miss Molly, it should be powerful.
