Don't complain about a champion being OP...
...if you aren't going to itemize against them correctly.
Seriously, Riot added an item specifically to counter Dr. Mundo. Fucking build Mortal Reminder.
"But he builds a lot of health! I should build Lord Dom's Regards!" Um no, you can still counter his health stacking with BotRK, plus you get a targeted and bonus attack speed so you can kite better.
Or don't. Just don't complain when Mundo is destroying you in the backline without you being able to damage him, k?
+ full tank yi
and 
is insane i mean anyone who would have told me that they would basically give a toned down version of grievious wound to last whisper id have called him insane its like tanks complaining they cant damage adc when they can build 
i know its underpowered atm on most you can still buy it. saw a rammus the other day kill a ezreal with it.
