Yes is somewhat steps on the wizards toes, but the wizard class is so loaded with features and benefits that they have feet everywhere.

I think there is a danger on focussing on what changed rather than what is. Is the wizard still a powerful class capable of doing really cool things that other classes can't? Yes. It is.

Compare this with something like the pact of the tome Warlock able to inscribe any ritual. This trampled all over the wizards thing of being the best at rituals but no one seems to mind as it got added sufficiently early.

If sorcerers had had this ability from the outset, would there be a campaign for it to be removed? Is it that the rule actually makes the game worse or is it that it changes the balance? Is it the new state people don't like or the direction of change?
