%attack vs %damage?

And since %s are additive, their impact is only equal if you started with the same total amount of +% attack and damage. If you already had +40% total damage (say, you're a cannoneer), +1% total damage adds less range than +1% attack, assuming you have less than +40% attack already.

I may be wrong about Cannon Overload giving +% damage, but the point is the same regarding the relationship of the two +%s.
