open lock spells? yeah, i recall them from morrowind. i also recall spellcrafting.
one of the first spells that i crafted in every mage walkthrough was open 100pts on touch. it basically added an extra button click needed to open locked stuff. removing any point of lockpicks and corresponding skill.
guess thats why they got rid of it.
to me, its logical from gameplay standpoint. as a roleplay warrior you have an armor, and a lot of hp, you should endure most attacks. as a roleplay mage, you have healing and protection spells. as a rogue, you have money, to buy potions, poisons and scrolls. how do you get money? well, from the locked chests of course!
there are mods, if you chose to use them, and if you cant - well, its your fault for picking a TES game on console, everyone would tell you thats a bad idea....
