The amount of random % damage reduction right now is pretty stupid.

I've been trying out a jungle yi build with PD, skirmishers, and ninja tabi- thats 44% reduction(not sure how it stacks but still) against autos and 32% against everything else BEFORE resists. It's basically impossible to duel anyone with this build as long as they scale with PD and I think it's pretty stupid how tanky champions can be especially considering people don't expect to do so little damage. I think one of the items at least should be changed so this isn't possible.
