what? Ezreal uses the attackspeed just like any AD carry would. If you aren't auto attacking with ezreal you aren't playing him right. Nunu only has one high mana cost ability which is his ice blast. Anything else gives has relatively low mana costs that a philo would regen back no problem. Carries such as vayne synergism and are shutdown by him the easiest. hit a carry with iceball and their damage drops significantly. The only way Ice blast pushes the lane is if you don't know how to drop minion aggro. toss ice blast and then run into the brush.

My stated problems on nunu are as follows:

Consume:
 * Heal amount
 * AP ratio
 * mana cost

Blood Boil:
 * Cost
 * Duration
 * Cooldown (he has 100% uptime with it currently)

Iceblast:
 * Cooldown (6 seconds)
 * Movement Speed slow amount (20 to 60%)
 * Attackspeed slow amount (25%)
 * Slow Duration (4 seconds on a 6 second cooldown)

Visionary and Absolute Zero are just fine. I could think of a way for certain aspects of him to remain strong while reducing his strengths. Make it so visionary reduces cooldowns on auto attacking but increase his cooldowns allot to compensate. Nunu is a champion bloated with Utility.
