Malphite + Frozen Heart + Randuin's is hilarious.

I spam my E and after I kill them I get to ask "why'd you stop attacking". And they're like "wtf it wouldn't let me attack". Because his E is 50% attack speed reduction, and Frozen Heart and Randuin's are 15% each. In total, 80% reduction. People who don't have attack speed items go down to one attack every 3-5 seconds. They just stand there and stop attacking. A fed Vayne with 9 kills had 1.44 attack speed then me with 3 kills E'd her to bring her down to 0.6 and I killed her easily.

For all you haters out there, Malphite is the champion for you. If you want to get really up close and personal then play Malphite support and max his E first.
