Magic is boring on a functional level because it's just pressing or holding buttons and it's boring on the mechanical level because you have to come up with meta-reasons to force yourself to engage in it. Even if you max out some strat like a cloak spell that autokills the dungeon for you it just makes the dungeon itself boring because now there's nothing in it to entertain you besides a few notes (which could get thrown around because of the spells, good luck finding them).

I like flashy lights so i'm a mage.
