It is a modifier on yor attack damage, the same as now. If you have 100 AD, 10% bonus damage is 10. If you have 250 AD, 10% is 25. Doing 10% on every attack is the same as doing 100% on every 10th attack or a 10% chance of doing 100. The difference with my idea is that mine is reliable.

I think Infinity Edge will be the only issue.
