Yes, so this way the game goes has nothing to do with an RPG.
You need a higher Intelligence for powerful Spells and the Intelligence is s special attribute for magician. I will not understand that a warrior can use Spells so good as a mage!
Your approach on what defines a role-playing game seems quite limited. In a purist's point of view, no computer role-playing game ever published might truly be a role-playing game. You apparently accept that computer games can be role-playing games, but only if they follow the D&D set of rules, more or less. Sorry, but that's pretty narrow-minded.
The classless skill system used in Larian's games grants the player more freedom to define the character's role. Nobody forces you to learn spells if you want to play a warrior. But if you have a character in mind who can both use weapons and cast spells, that's easily possible. It's comparable to multi-classed or dual-classed characters in the D&D system, but simpler and much more adaptable to what the player has in mind.
