ITT: We suggest radical changes to OP champions.
Let's make something different. Instead of the dozens of threads demanding the gutting of OP champions, let's try and change them into balanceness in the craziest ways possible.
I'll lead by example with Zed:
R: Death Mark - The mark will only explode if Zed deals enough damage to kill the target.
Essentially, if Zed can't get the targeted enemy low enough that his ultimate would kill them, the mark wouldn't proc at all, and he wouldn't do any damage (besides what his skills deal).
This would mean that if Zed is behind, he can't chunk enemies for 80% of their HP then just click R and run away. He'd have to actually commit and gasp take risks.
