You really want Heim to be this pointlessly broken?

I'm sorry, but you nerf Malzahar because he's an "uninteractive" waveclear machine that presses two buttons to kill anyone who tries to stop him, and then you turn Heimerdinger into the exact same thing? How stupid are you?
Since you can't bother to keep the game in a decent spot, let me alert you: just wait until people find out about the Conqueror interaction! Every single turret attack procs it. Run Conqueror/Triumph/Legend: Tenacity/Coup+Transcendence/Gathering Storm and get that 80% winrate, why don't you?
