Malphite is not a ducking burst mage
Remove his ap damage to a minimum. His ult is fucking way to simplistic for him to be able to do 2k damage anywhere he wants during a team fight. He is a tank meant to engage as a tank, not a burst mage who can one shot entire teams. Make him a tank. A tank. Do you know what tanks do? They tank. A tank tanks. A tank isn’t a burst mage. A tank is a tank. Make malphite a tank.
