I decided that 5 stacks was too few, and stunning that often would either make the enemy player ragequit or cause 5v1 ganks on you on every occasion. But seriously, I think 8 is fine as it is. But thanks for the % ArPen suggestion, I was reluctant to change the type of penetration it gives, but It really seems like a lot better option.
