most groups do not use primal in my experience as they literally do not know what it is as they got told to never think about 4e.I think that's a matter of perception. I see the sorcerer as an alternative to the wizard for players who want that alternative. The similarities in the spells doesn't bother me because the distinctions are made in other ways, and that's not different than the similarities with a fighter and barbarian.
We still end up with hex blades demonstrating that smite spells and smiting didn't step on paladin toes because the other differences are important. Just name sure there are other differences.
Rangers left lore behind in energy edition.
Most groups still use primal as an energy source, the n my experience. It's pretty cosmetic.
