I used to main mundo, was fun while I was playing him but it got boring after a while, right now I prefer to play people that I can easily solo lanes, gank and potentially carry my team such as olaf (who doesn't love having more attack speed the lower your life is and a skill that kicks in awesome lifesteal and attack damage based on how much health you have ) and AP master yi.( tanking with meditate while using his Q to do insane damage )
