Can we tweak Randuin's Omen a little?
has been kind of neglected, but looking at the passive the other day made me think. What if riot could tweak its interaction with IE such that all of the true damage that IE does is part of the 20% of crit damage that RO's passive blocks? Maybe drop its armor to 50 to keep it from being overbearing to an ADC. This would be a small way to help tanks.
was changed to not waste a passive when built with omen because what you just said is reduce true damage taken from crits with omen but increase physical damage slightly which is compensation that happens to benefit the use of lifesteal
