So about AP Malphite.

I do not think it is broken. Have something with mobility and he is useless or striagh up dead once he misses his ult. WIth enough AP Morgana's BS can also save you.

But there are 2 things that bother me.

1. That he is just a damn annoyance who acts like a fiddlesticks on steroids with him ulting out of nowhere to one shot.
2. That the AP variant as apperantly stronger than his tank version. He is played in the jungle, where is almost exclusively an AP Assassin, but also still has a home on toplane, where you might see him as a tank, but with what Champion.GG tracked, he is even mote successful on AP there.

The second point really annoys me because it just screams "Failed Design". His ult is supposed to be an engage, but after it, there is nothing left to follow up on. I highly doubt anyone playing him in lower ELO even knows what his E does besides AOE damage. And his Q is really mainly a burst/poke tool that way. The change on his W to better his waveclear has also instead given him an AOE burst clap.
