IMHO his passive is OP if you build him as a tank. I mean, imagine you go full tank, you can and will have about 200 armor and MR more than an adc. This translates to 400 true (!) damage to an adc who will probably fall withing 5 seconds, while dealing very little damage to you because of your 300 armor. Same goes with mages, they may have an Hourglass and an abyssal scepter, but they wont be able to melt through your MR as fast as you melt through their health with still 300 true damage per AA.
