Cassiopeia- who is she? What is her identity?
Hoh boy. Cassiopeia, Cassiopeia. Guys, I love this champ. I do. She was the first champ I bought with IP and when I think League I think of the nostalgia of picking her back at the end of season 3. Anyways, I've been following all discussion about her and have commented a few times, but honestly... I don't know if the Cassiopeia playerbase can come to a consensus. Some like King Kobra say her High DPS with Twin Fang was the correct direction to take her kit as people picked her for her raw damage output. Others like Ginga and Canastus played Cassiopeia as a poke mage with her poisons and say this rework destroys that. While the rework has it's problems, particular the passive, as a general direction of DPS mage I think it can work and a hypercarry DPS mage might be fun.
HOWEVER!
...Is this a good gameplay niche for Cassiopeia? I don't know. The thing that's stood out about Cassiopeia to me, what I like about her is her intelligence. She has this certain shrewdness that just says "Cassiopeia." Her personality aligns really well with the snake motif, as well. That's why I loved her lore judgement and I adore her new voice over. (Still provided by the lovely Karen Strassman) She is a manipulator. Confident, shrewd, opportunistic. The only thing that I don't like was that her new lore with Shurima... just didn't seem very smart for her otherwise clever nature. That's more of a storytelling issue than anything to do with Cassiopeia's personality, though.
Anyways, personality wise I don't know if "manipulative, seductive, shrewd temptress" is a match for AP hyper carry. I don't mean to be condescending as hell, but I don't know. Thing is, I feel like DPS mage niche came from the fact that she could be a DPS mage before. Story wise I believe a poison poke mage would fit better, strictly speaking.
But it's not so simple. Cassiopeia's base line at the moment is "Snake Mage." Sure she has a bit of Gorgon with her ultimate, Petrifying Gaze. And she looks mostly like a Lamia, specifically, with her cowl of sorts on her head and half serpentine body, but that's about it. Do snakes use poison, or more specifically venom? Sure, but not all species do. Anyways, Cassiopeia as a snake who uses venom. Base line. Now here is where things get very, VERY, tricky.
Storytelling wise, Snakes are associated with shrewdness, deception, and perhaps cowardice. Snakes in real life though... That's another story. You can't really argue whether their fangs or venom is more important to "kill" so to speak among snake species that do use venom. So meh. From what I can see, Cassiopeia as a poke mage or DPS mage can make good sense regardless of which of the two is chosen, but perhaps the former makes a bit more sense.
Gameplay wise, before her rework Cassiopeia was inconsistent. I acknowledge it. Her Q and W were poke/zoning DoT, poision spells. Her E was a standard nuke on a refreshable cooldown to be a DPS mage. Her ultimate was Medusa/Gorgon inspired and given a slightly longer duration stun because it was harder to land. A devasting counterattack/countengage or defensive tool was what her original designer, Brackhar, wanted. Now, it's more or less the same, except the number shifts have forced players into the DPS mage style playstyle. There's nothing wrong with that playstyle, but it leaves a sour taste in those who preferred Cassiopeia as a posion poke mage.
Except vice versa could also be true on a second revision, and that's why this is so difficult.
This can stand as the TL;DR for the entire post. Cassiopeia, for better or worse, had very versatile builds and playstyles before her rework. With it, despite it's other small problems, comes the big and only true meaningful problem of that half of Cassiopeia's fanbase have had the DPS mage playstyle they don't like forced upon them. And you can't turn her into a poison poke-mage because the other half of her fanbase will be upset. I honestly think that maybe we should just revert her rework and leave her with her slightly incoherent, inconsistent, but extremely fun kit she had before. Besides, not everyone has to be the best at one thing. Cassiopeia was and can be a generalist mage, like Brand, if that's the best way to go. With her sheer numbers on her damage before, both fanbases can get away with playing mostly how'd they like. Basically, I think, and hope, that getting almost satisfaction for both bases is overall better than the complete satisfaction of one half and complete dissatisfaction of the other half is better. And perhaps it's the best that can be done.
