% reduction does stack multiplicitavely and is applied AFTER armor and magic resistance. So 50% from armor/mr, then that 50% is reduced by 75% for 87.5% reduction, then what remains is reduced by 15% for about 87.7% reduction. Leviathan gives only 1% more reduction compared to true damage in the end if I did the math right. The primary advantage is that % damage reduction is not affected by armor or magic penetration or reduction. Other than that it's actually better without other resistances, which is probably why we don't see this often.
