I would like to start by saying, "SOMEONE PLEASE HELP ME I DO NOT UNDERSTAND.".
Why do people build Master Yi AP!? I just don't get! Master Yi is an AD focused DPS. Under no circumstances should anyone build Yi AP! Maybe there is some sort of hidden secret I do not know, but it never makes me more frustrated than to see an AP Yi feed on my team or even the enemy's team.

YES I KNOW THAT HIS Alpha Strike SCALES OFF OF AP, BUT WHAT ABOUT Wuju Stlye AND Highlander!?!?! AND Meditate IS NOT A VALID ARGUMENT FOR WHY AP YI IS GOOD. "OMG YOU CAN SIT STILL AND REGEN HEALTH FOR 5 SECONDS DURING A TEAM FIGHT WHILE YOUR "Q" IS OFF OF COOL DOWN. YOU'RE BASICALLY INVINCIBLE BRO." Yeah, well you're also an immobile target who can be picked off at the end of the team fight. GOOD JOB YOU STUPID ******.

I honestly just think that people enjoy playing AP Master Yi because his Alpha Strike can KS really hard with a lot of AP, and it makes your K/D look really nice. In closing, if you play AP Master Yi, GO CLIMB IN A ******** HOLE AND DIE. QUIT BREATHING MY OXYGEN YOU SCUM SUCKING VERMIN.
