WHAT THE HELL IS WRONG WITH THE NEW MORDE

I just finished playing my 2nd promo game, which I lost of course. My top Renekton, who was pretty good, couldn't scratch their Morde. I played Xin jungle so I ganked him twice early, killed him both times. After 5 minutes, Morde farmed up trinity and one giant belt. I came ganking. He killed us both. He gave around 2000 DMG with Q to me. Then finished off Rene without much trouble. Now I ask you. RITO. Y. U. DO. DIS. ?! After trinity, he went full tank and proceeded to one shot my soraka with his Q and easy 1v3-ing. HOW, but HOW can a practically full tank champ who was ganked and killed 2 times in early game go full tank and ONE SHOT PEOPLE WITH HIS 2000 DMG Q?! HOW? WHY? It was just ridiculous, the dude also said it. Something is broken with that champ, something like that cannot exist in a, what Riot want to accomplish, "balanced" game like LoL. Something is deeply broken and needs to be fixed. ASAP. It's something like ap tristana way back in S2 I think. When every minion that exploded gave it's own dmg to everyone surrounding. U could one shot people just by jumping into them while they were standing close to a wave of minions that were low. But this is S5, so PLEASE RITO, FIX IT!!!
