I agree completely. Are there 3rd-party products that provide an alternative divine magic system that's mechanically different from arcane, or vice versa?Personally, I dislike D&D's decision to use the same mechanical model for all types of magic. I would love to see more diverse mechanics, not just for psionics but for sorcery, wizardry, divine magic, and others. I enjoy roleplaying, but I also like engaging with mechanics for their own sake; I don't regard them as disposable and interchangeable. Class mechanics should evoke the flavor of that class.
I don't need the systems to be radically different. I'm sure there's a way to split the two but still using the basic way magic works in 5E. the problem might be in making sure arcane isn't inherently better overall than divine, and vice versa.
Honestly, I would like most or all magic to be like this. You should have to make a choice about what kind of magic you're going to focus on, be especially good (powerful, flexible) in that area, and less so in others. I guess this is true to some degree already in 5E, but all told it comes across as not very different, in my experience.I would prefer a non-spell-based psionics system.
Spells are discrete things. You cast fireball, and you get a 20-foot-radius ball of fire somewhere far away doing X amount of damage. You cast haste, and the target moves faster and can do more stuff. It is trivial to create a character who can do both of these things.
Psionics, at least to me, lean more on sci-fi and superhero tropes. In those, it is more common to have one (or rarely multiple) core power(s) that can be expressed in different ways. Xavier is a telepath. He can communicate telepathically, read minds, create mental blasts, create mental illusions, project astrally, and use his telepathy in a number of other ways. In the OG Marvel RPG, this was expressed as having the Telepathy power and a number of "Power stunts" based on that power. But he can't move things with his mind, or see the future, or walk through walls, or heal his legs.
