-Eldritch Knights will feel so special when any other Fighter can be a spellcaster too and steal their unique perks, while also using their own Battlemaster or Champion stuff the EK doesn't get.
This, really.
If I'm not wrong barbarian and monks are the only classes in the PHB that doesn't have any sublass that can use magic. That's 2 classes out of 12. All other can access to magic and their own "class/subclass spell list".
Once again, allowing everyone to cast spells (and wizards to write divine spells in their book) just tone down what makes classes/subclasses unique and trivialize our choices... Like many other things.
