The game is balanced, dunno what the argument here is.
You wanna play as a thief you will probably svck in close combat, but will do massive damage from stealthy hits.
You play a mage you should know that you will need to mix with one of the other archetypes or go full mage, utilizing both defensive and offensive magic.
You play a warrior you know that you can't sneak up on things or hit anything from a range in general. Warriors are crippled more by frost magic due to their inability to hit things from a range and their dependence on stamina. However, he can take physical hits the best out of the three.
As far as outside of combat goes, thief-esque characters have speech, pickpocket, and lockpick which all help to complete quests. Mages have Illusion and Alteration for overcoming obstacles outside of combat. And the warrior? His only way to complete quests is by killing stuff.
There are things even deeper than this that balance the game further, but I can't be asked to name them all.
And on top of that, why are we even talking about archetypes? Classes are no longer there so you can do whatever you want to do. The whole point is doing what you want, and what feels natural, what feels fun.
Personally, I can't play as a warrior. It is just too cliche for me. I always play with a mix of stealth and magic. Start the fight off by sniping the opponent, and if they find you, burn them. Use Fury to make enemies kill themselves. Use speech to finish quests early. Enchant weapons and armor!
