2. Is there a good reason that changing it improves the game?
...So, no thanks- I'll keep Bigby's grasping hand, Tenser's floating disc and Nirrighan's dismemberment as they are.
I'm not saying change the names, I'm saying give us some freaking blurbs/stories/whatever to initiate EVERYONE who may only know the name (or not even that) with them.
Give us something to make them meaningful again instead of "just that name on that spell."
