Cassiopeia Rework...

P - "Cassiopeia gains Movement Speed per level, but she cannot purchase Boots items." Q - "Cassiopeia blasts an area with Poison after a brief delay, granting her increased Movement Speed if she hits an enemy champion."

W - "Cassiopeia releases several clouds of poison, lightly damaging and slowing any enemy that happens to pass through them. Enemies affected by this poison are Grounded, losing the ability to use Movement abilities." Repertoir on reddit: "It is intended to cover all blink, dash, and teleport type spells, including (but not limited to) Lucian E, Ezreal E, Summoner Flash, Bard Magical Journey, Thresh Dark Passage, and Summoner Teleport." Repertoir on reddit: "Aside from the addition of the Grounded debuff, the W you see on PBE in this build is NOT representative of the spell that she's going to ship with." E- "Cassiopeia lets loose an attack that deals increased damage to Poisoned targets and heals her for a percentage of the damage dealt. If the target dies from this attack, Cassiopeia regains Mana." [Bugged in today's update. Intended cooldown is 1 second.] R - "Cassiopeia releases a swirl of magical energy from her eyes, stunning any enemies in front of her that are facing her and slowing any others with their back turned."**

Giving a mage compensation for movement speed so they don't have to purchase boots is insane. Think about this, you could buy a lot of things that will either increase your damage significantly or some defense like GA. Another thing I would like to bring up is the W mobility counter. I could see this making her kind of like Lux. You land one spell and you get to dump on the enemy, if her E is similar to what it is now this will make her very dominant in all stages of the game. Looks cool, but seems overloaded. Still, I am excited to play her, not so much against her. Thinking about possible items to replace boots as well.

Here are some I am thinking about.
