10 wins in a row as malphite. Of course he's not op he's balanced, there's so much you can do against his "hover cursor over you to aquire 300gold" Like flash, and not being there in the first place.
And being able to build literally anything for the exact same playstyle is just a perfect feature, he also has a unique passive to make laning against him super fucking boring.
I actually think he's so fun and fair and interesting design, because you can get the exact same experience fighting me in lane when I pick malphite as going outside grabbing a rock and actually headbutting it for 15-20 minutes, because every game was an early surrender, out of 10 games 2 were played out and I just fountain camp by 32.
tl:dr who the fuck made malphite? what a fuckin psychopath
