Why are you nerfing Cassiopeia?

i get it, she has kind of a root on her W and everything. i love playing Cassio how she is now, her only problem is that games are too short and it's hard to stack her passive up fully. that being said, her new passive is fucking stupid. its actually a direct nerf. you already build movement speed items like ludens or swifties on her, if you want movement speed, and get speed boosts from her kit. now you've taken away her free CDR. i understand that the sixth item slot will be worth something and give you a lot of AP in the absence of her missing the passive % AP bonus, but here's the problem riot.. do you know how many games you're actually going to be able to get six items in? so now you've taken a champ with high relative late game power, in a meta where games last 25 minutes and taken away the early boosts that things like the magic pen on sorc shoes or cdr on lucidity boots. you've made it to where you can no longer get the other helpful bonuses from boots like tenacity, cooldowns on summoner spells and magic pen in her early game. how do you get any kind of tenacity on cassiopeia now? is moonflair spellblade gonna be added to summoners rift and howling abyss? and yes people actually DO build different kinds of boots on mages sometimes. wow, what a surprise. you've also completely changed mana regen and directly nerfed her synergy with tear of the goddess. RIP Cassiopeia. this entire rework looks like garbage imo.
