Wow, see yeah this isn't Fable, this is TES. By trying to teach us how to play, you're forgetting how they intended to design the game. Everything you're saying in thsi paragraph is stuff bethesda is against
I'm not telling anyone how to play but there is a limit of how you can expect to play anything. That'd be like me making an archer and saying I DON"T WANT TO SNEAK EVER OR WEAR ANY ARMOR OR TAKE ANY PERKS BECAUSE THATS HOW I WANT TO PLAY.
No.
If your going to play a mage you need to do whatever you can to survive. Obviously tougher battles are gonna use magic potions, stock up. Bring a companion, you know that enemies aren't going to just stand around as you cast at them so you need something to draw attention.
By the end I can now summon 2 creatures with advanced health and have a companion. I have a veriatible army for each enemy to get through before they have a chance at getting to me. While my friends are fighting i'm right behind them calling down blizzards and shouting enemies to death. Its insanely fun, I have restoration and glyphs to place on the ground. While illusion for tight moments.
The game was definitely not built for you to limit yourself. Yeah you can play how you want but you aren't supposed to go in thinking "i will never use conjuration and i will be a pure lightning mage". That's not what was intended, if you notice there are no classes.
You are supposed to jump in, find a prefered way of killing things but use everything available to you. If you love magic don the robes since they increase many magic related abilities. Bring a sword for dire moments. Take mage armor and increase your health.
I also rolled a archer focused character and I have to increase my health as well. Health is not a "warrior only" stat. Its the general ability for you to take a hit. If you just invest everything into magic then you are gimping your own self and I feel no sorrow for your plight.
I'm gonna get off the boards soon though and continue casting blizzards and watching enemies bow before my magics. Have fun complaining about not being able to run around as a naked fist fighter and still survive lol.
I'm telling you, if you want to be a mage get rid of this pure notion. There isn't a pure warrior either or else many a dragon will swoon in and eat you alive. Neither is it pure archer as you are slow while pulling back a bow so you HAVE to take a sword with you or some form of secondary protection.
Mage is no different, it has short comming just like the other archtypes that must be filled to survive effectively.
