Cassiopeia Re-Rework Ideas

Right now Cassiopeia is in a horrible state and the upcoming set of nerfs will ruin her. Her main problems are that she's squishy, she's immobile, her laningphase is going to be horrible with the upcoming set of nerfs, she deals a high amount of damage, and is just unfun to play as or against. So the ideas i have are to fix these problems that she has and just to help her in a whole. Base Health rescaled to 380-2180 giving her a weaker and a need for a safer early game, but gives her a stronger late game. Base Mana rescaled to 400-1400 allowing Cass to cast more of the spells that she needs for damage Health regen rescaled to 5-15 Mana regen rescaled to 8.-21 Armor 30-78 Because of her small amount of early game health her starting armor is drastically higher but her late game armor is reduced because of her large late game health pool. Movement speed increased to 350 because of the bonus movement speed from Q being removed this is just to help her out. Passive Aspect Of The Serpent Consecutive spellcasts increase Cassiopeia's damage by 5% for seven seconds stacking up to 25% bonus damage. This change is to give Cass the essence of her current passive but more healthy, this change gives Cass times of highs and lows. Q Noxious blast Cassiopeia causes an explosion of toxic blast in an area lowering the magic resist of enemies caught by 3/6/9/12/15% and dealing 10/20/30/40/50 (+13%ap) each second for 3 seconds and damage increases by 1% for each 1% health the enemies are missing. Additionally Twin fang casts on targets afflicted by Noxious Blast's poison increase poison duration by .75 seconds capping at a bonus 3 seconds. W Miasma Cassiopeia unleashes a poison toxic gas on an area that expands for 6 seconds enemies caught are blinded as long as they are in the cloud and take between 50/60/70/80/90(+45%ap) - 100/130/160/190/220 (80%ap) depending on duration in Miasma. E Twin Fang Cassiopeia unleashes a pair of snake fangs at target enemy dealing 20/30/40/50/60 (15%ap) magic damage and if the target is poisoned the damage is tripled and the cooldown is refreshed. If cassiopeia is below 40% health twin fang heals Cassiopeia for 5/10/15/20/25 (5%ap). R Petrifying Gaze Cassiopeia gazes in target direction dealing 160/240/360(+60%ap) stunning targets facing her for 2 seconds and slowing enemies with their backs turned by 50/60/70% for 2 seconds. Each champion hit grants Cassiopeia 15/20/25 bonus armor and magic resist. The changes all help her gameplay and allow her to be more of a mage instead of a lategame E machine dealing 094387t938798349834998247598724 damage and improve her as a whole so yeah bye.
