You can only add/remove 1 type effectiveness/resistance, which one would you chose for better type balace?

Concept in the title.

Basically you can only use 1 out of those 4 options (and only 1 time):

-> Turning neutral damage into super effectiveness

-> Turning super effectiveness into neutal damage

-> Turning neutral damage into resistance or

-> Turning resistance into neutral damage

If you want you can write multiple type interaction changes too (feel free to do so). But it would be greatly appreciated if you still specify your most preferred change.

Bonus points if it still makes sense flavor-wise. (for example Fire dealing only neutral damage against Ice might be nice, but doesn't make much sense tbf)
