warriors have it quite hard at least until they can afford powerful enchantments to their gear, by which they have to invest perks in enchanting. im level 20 sword and board warrior with some knowledge in smithing so improved my gear some armor. if i encounter high tier enemy its rly life and death...one shot even blocked rips one fifth of health. and in dungeons there are ususally several other low tier enemies with them. if i dont drink potion thoroughly i cant survive.

warriors are especially weak when being attacked by many. mages can crowd control and deal multiple damage, thief can takr down target one by one(or at least severely damage some portion of enemy group before fighting).
