Lulu is actually way too overpowered

Over the course of these weeks i've played against countless lulu supports. And lulu has been picked nearly every game. Here is the gist of my argument;

• Her Cooldowns are too low for shield and her whimsy is a ridiculously low cooldown and the mana cost is non existent. Her ability to peel adc's simply does not let them die. If she builds items with shields like mikaels, and uses her shield with ultimate, there is almost no chance of killing the adc. Regardless of how much burst your team has. The move speed and attack speed on allies is just completely busted in the fact that it can be used all the time. But most importantly her whimsy making enemies unable to cast or attack at all, is such a LONG duration. And the ability is such a low cooldown that qss won't really do much for you unless you kill her fast enough. She simply needs a cooldown and duration of spells nerf.
